yup, they did get hot, I believe timing was ok, I think it ran too lean. All the grey in those chambers matches a lean condition. Mechanical pump wouldn't keep up, it ran out of gas after 1st and second gear at wot and fell on it's face. I will not let that condition go unchecked again. That's the reason for the electric pump install, too little too late I guess. This could be a blessing in disguise, if it would have ran I would have beat on it hard as usual. Those valves getting sucked in could have been much worse than what I have now, specially over 7200 r's and at speed on the road.

396/427 block is going in for sonic testing, if it passes it and the heads are getting magged, then im off and running! :)

Thank you George!

Block, heads and intake will be put to good use! :)

Thinking of buying a set of eagle 5140 rods for 300 bucks.
I'd have enough into mine after mag testing, clean up/sizing and new rod bolts to make this very enticing. Anybody have any experience or hear any issues with these? 427 build, 6200-6500 max rpm, 450-500hp is my target.

These pistons are going in.

http://www.summitracing.com/parts/slp-l2300nf30

Heads are 215's

Now onto cam selection. Hyd flat tappet. 2000-6000, 2500-6500. Somewhere in that range. Going to be a 4 speed car now as well. Have 3.73's in the diff.

Isky Mega 280 is on top of the short list for sure.

nothing large enough. Thinking I need an 800 at least. I have a 700dp and a 750 vac secondary, and a bastard 3310-1 of some iteration, looks to be a bolted together Frankenstein from many carbs. I am not going too lean again, 800 or 850, pig rich wont bother me after looking at my 327 fuel starved exhaust valves.

Those rods will be fine, my 427 was seeing well north of 7000 RPM's with just thumb rods with ARP's. An 800 DP'r with a little jetting and larger squirters would be a hard hitting combo on top of that with a 280 isky bump stick. If you buy a new carb, just go with a 950 HP off of Holley's Ebay reman site. Killer deals for killer carbs.

A 396/375 horse power factory style mechanical pump would work fine for any street use but doubt it would support 1/4 mile track blasts.

If you go the Isky, Advance it another 4 degrees to be on a 100-101 ICL. It will hit super hard on the throttle mash.

22-24 initial advance with another 12-14 mechanical in by 3000 RPM's

Awesome info, thank you Doc!

I have a holley blue pump and filter mounted , wired up and ready, knew the 327 was running out of fuel, much worse than I thought though.

Everybody likes that isky stick, guess I'll give it a go! :)

Called and talked to isky tech yesterday, they spec a 395psi open valve spring for that cam, and their solid rollers that go to 8500. Seems to be a lot of spring for a hydraulic lifter? They said it would be fine. Thoughts? Comp 924's are on the heads, they have 350psi open. If they are not sufficient then I'll get the springs isky specs for that cam.

Short block is in the shop being bored honed balanced turned polished and the pistons hung.

327 has been removed and I got it to break free and rotate. Once I got the rods and pistons out the crank spun effortlessly and kept right on spinning freely with a slow stop. No abrupt stickiness anywhere. Rod and main bearings looked great, crank surface looked like it just came off the polishing machine. Very happy about that.

The three exh valves that were elongated due to heat also started slappin the pistons in the cut out area. Just a matter of time till she grenade.

Honed out the two bad block holes with a brush hone real quick to remove the rust and get a better idea of the pitting. should take a 60 over bore to clean up, if it passes mag testing. Not as bad as I thought.

Now, on to this for the time being while I wait for the machine shop and order more parts for my car. :)

This is my moms car, been sitting in a garage for about 25 years and had probably 200 miles put on it that whole time. And no maintenance, my dad is horrible at mechanical knowledge and skills.

Enough of that crap, im putting some miles on her. Picked it up a week ago and it ran rough.

Replaced the alternator, plugs, wires, cap and rotor. Rebuilt a carb I got from a member here, 750 vac secondary. The carb on it was too far gone.

Waterpump bearing is howling like the alternator was, it's next along with a fan shroud and a small tach and some other small niceties.

Gas is crap now, im thinking its much leaner than it used to be with all the bullshit they put in it. Mixing 50/50 with VP110, she runs a lot better now.

So i'll be bombing around in this baby till the weather turns for winter. :)

It is sweet aint it! Numbers matching car. I have the original motor and trans here at my place. Both were whipped and are as they were built from the factory. I put a used 62-72 crate 327 in it and a new cam with a rebuilt glide before they took it in for the restoration. Nothing special though, 327 glide car from the factory. Perfect cruiser. Drove this car every summer until it got restored. Got a stock Kleenex holder in it, rotates out for access with a chevy emblem on it. Never seen one of those before. Kinda cool.

After I'm done with my cars 427 4speed swap, the stock engine and trans are getting redone and installed back in her.

Done dinkin with moms car, BBC time for my baby!

Machine work and balancing is done. time to pay the piper. picking up the rotating assembly and block this week.

T350 has been freshened and beefed up a bit. Long enough to last until I gather the rest of the parts for a 4 speed swap next summer. 3k stall behind a small block, can I assume another 500 or so slippage with a big block in front of it?

Carb's on the way.

Straub phone call time in a couple weeks.

Headers and radiator are the next big ticket items, then it's all down to the nitty gritty. :)

I love this thing! Such an odd color combo, but it's really cool. Hope to see it in person some day. Sadly, another summer has past without me putting mine together.

Got the rotating assy back from the shop. Very nice work. Forgot the tie downs so I'll get the block next week. .060 over, decks squared, honed for moly's.

Got all the crank throws to within .001 of each other, they were off by .010. Didn't have to add Mallory, the 396 crank was 30 grams off of the 427 spec. So they welded in the previous drilled holes to get the balancing weights right.

No brainer, by the time i would have had my rods reconned, the new eagles were a hundred more.

Ultra 950hp and dougs 2" headers on the way.

Aluminum rad and a call to Straub next week for cam and lifters and I'll have all the high buck stuff done.

New front SS springs, bushings and shocks are going in before I drop the 427 in it.

Gonna be busy as hell here pretty quick!

Should have bought stock in Summit before I started this project, LOL!

Picking up the block next week, Then when my round metal stock gets here I have to build some long bushings for the engine stand. Mounting assy holes/tubes are 5/8" ID x 4+ inches long, bolts are 3/8", way too much wiggle room and slop for my piece of mind. cutting and drilling out the stock to fit the length of the engine stand tubing to alleviate the slop.

Then it's on the stand for fit up, clearance checking then assembly.

New front springs, bushings and shocks have to be done before the heavy weight goes in it. It was already in the weeds with the sb.

Will be busy as hell soon. Should be a blast!

Engine set up so far:

427 build in progress, .060 over honed for molys with plates, line honed, 2-bolt studded mains, decked .014 to square, forged L2300's on eagle rods, 215's w/ 924's, 2.19-1.88, RPM Air Gap, 950 ultra hp, squishy set up, comp ultra pro mags, ati superdamper, steel crank throws squared to 3.765, rotating assy balanced to 2 grams, dougs headers through 3" out the back.

Cam
Lift .600/.570
Adv. 288/300
.050 229/241
Lobe Sep 109

Freshened T350 w/3K stall - M20 going in summer of 2015.
Fresh 12 bolt w/3.73's
