RE: Bskredsvig' 68 build

Well the M22 was not the old trans from my buddy'all FJ40. Turned out to be a Saginaw 3 speed from the late 60's. I grabbed it anyway and the motor it was attatched to. The guy said the motor was a 305 but running the casting number showed up as a early 70's 350. Has a decent aluminum intake on it and all the brackets and pulleys. A friend of mine is looking for a rebuildable sbc for his Toyota project so off to his house it went and I just stuck the tranny in the corner of my shop for now. 

Drove the car some more yesterday. Haven't looked into the grounds yet because it was daylight and everything works fine without the lights on. Maybe today.

Car is stumbling a lot at higher rpm or 3/4+ throttle. I'm assuming it's just too much fuel from that qjet for the massive 307......  Does anyone have any suggestions as to jetting or metering rods? I know it's hard to diagnose from a computer screen. I may play with the timing a little too. I'm at 4 degrees at idle. Might try to add more until it pings and see how it is. 

 

Went to to the store real quick this morning and a kid in an iroc thought he was pretty cool. That 307 showed him up pretty good drifting around a corner and left him in a big cloud of tire smoke.

If its throwing black smoke then its fuel, I doubt that's the issue as the Qjet is a pretty good carb (shut up Dave).  If you're still running points, I'd look at the ignition system first.

It's still points.  I filed them when I first got it running but that is it. Guess I'll look into that; make sure the advance is working, etc. Can't see the smoke but the pipe tips are pretty black.

Timing/good spark first, then the carb. Try 12 degrees initial without the advance can at idle.

Wet sanded and buffed the whole car except roof this week. No show paint but it shines and looks much less like a turd.

Anyone know the differences, other than appearance, between wiper motors? I picked one up the other day that plugs right in and mounts up, but it’s all squared and stamped. The one that came out of my car is cast aluminum. There’s a couple other minor differences, but that’s the basics. 

May assumption is it’s just a supplier difference based on the plant the car was built in or aftermarket vs oem. Both speeds on my wipers work with the new motor, as well as fluid pump. Just curious. 

Included internet pics of each.

the small square one is for non-hidden wipers, the bigger round one is for self parking hidden wipers.

I'm not sure if the arms & linkages are different between the two or not.

Picked up an M21 with hurst shifter this weekend for way too cheap. A little closer to my 4 speed and big block aspirations. Now pedals and flywheel and I’m rowing gears. 

Got the other springs I ordered installed and they were super tall. My wife cane out and asked why the rear end was so jacked up and said it looks like shit. So those springs went back and just going with what was in there; at least I know where they sat. Tank is back in and all the soft lines replaced. Changed rearend fluid and imspected gears. Everything looks good and confirmed 3.08:1 gears. 

Only bad news: 307 picked up a tick at idle after a high rpm run. Goes away shortly but concerning. Oil was 1/2 quart low and who knows the shape of the filter. Changed oil and filter but haven’t been able to drive it since.

 Nice score! I miss driving my 69 with a 396 and 4 speed......a stick would be fun behind the 454 I have now biggrin

So the reason for my big block questions post; my 307 has been feeling like it has less and less power. It also has an intermittent tick and popping through the carb and just runs terrible above 1/2 throttle. I had my suspicions but checked timing and dwell and they were fine so I was pretty sure I may have a bad cam lobe or lobes. I pulled the valve covers tonight and the #3 Exhaust is definitely jacked.  Video link below. 

Basically now I’m just trying to see what route is best so I can drive it this summer still. New cam for 307 is out of the question. So I have my small block I was thinking about building a few months ago. I traded for a crank with bearings and a gasket kit so I’d only need a cam and lifters, rings, timing set and oil pump. Or go the bbc route if I can swing it budget friendly enough. I figure whichever one, I’ll put my muncie in at the same time so I’d need to factor in a clutch and flywheel for either motor. If I don’t do the bbc now, I’d wait a year or two and save up a little more for it.   Decisions.

That is a worn exhaust lobe, exactly the reason it is popping back through the carb.

Went and talked to Terry Malm this morning. Stripped my block and heads and bringing them to him later today. He thinks the lunati 60204 will be a good cam choice. Bigger valves and a little headwork. Resize rods, bore .030” to clean up the cylinders, deck the block then decide on pistons after knowing head cc and deck height to get between 9.5-10:1. Should be able to get it all done right in my current budget so that’s nice. 

I’ll be needing some parts if anyone has some for sale? 

Air gap or other decent intake. 

Chevelle oil pan. 

Full length chevelle bbc headers. 

Holley 750+ carb. 

Chevelle bbc motor mounts (frame side and engine side). 

I’d like some fabbed style aluminum valve covers. 

Also a flywheel and clutch but I’ll likely buy that new.

Awesome!!! Sorry i don't have any of the stuff to help ya build it, but thats awesome progress!!!! I can't wait to see how the voodoo 204 is in your car, sounds like they will be very similar builds except for the compression and cam!

 

Its the ugly 68 club!

I have the cam kit, timing chain, and an oil pump if you haven't gotten them yet?

Met with Thor yesterday and picked up a good haul of parts I was going to buy anyway. Started rebuilding my muncie this weekend too; internals inspected and got the cases cleaned up. Getting closer.
