Yeah I was sad to see the May Norwalk Buick event go away. It had a decent car show and swap meet and racing to boot. You figure the GNs are getting to be about 30 or so years old now and I get the impression that the latest turbo Buicks aren't being modified/collected in the numbers that the...
Oh well, I tried! As long as I have the engine out with the cam easy to uninstall-install I might as well get a new cam/lifters. That way I know for sure what I have and there's no guesswork involved. I used to get stuff from you way back at the Nationals in BG so I now need to find my flow...
I didn't use a "stop" to determine TDC. (didn't have one handy) I used a dial indicator resting on the #1 piston and took the dwell degrees (where the engine is at TDC) from the degree wheel and "halved them" so that I could get as close to TDC as possible. I've gone through about every cam...
Pic 1 is TDC
Pic 2 is intake open at 0.50"
Pic 3 is intake closing at 0.50"
Pic 4 is exhaust open at 0.50"
Pic 5 is exhaust closing at 0.50"
Intake lift is .222" and exhaust lift is .229" lift
For the intake and exhaust closing measurements, I rotated the engine until the cam lobe ramped all...
Chuck, I'll get a chance later to look for can stampings.
Still confused on the duration readings. I started at TDC of #1 and did what EarlBrown said and the degree wheel spun just over 1 full turn (374 degrees) going from base circle at #1 TDC to .050" lift. Then the degree wheel went from 14...
Bought an engine and trying to figure out which cam is in there. I bought a Comp Cams degree wheel and have been trying to figure out the whole procedure. I used a dial indicator on the #1 piston to set TDC on the degree wheel and wire attached to the block. I noticed the You Tube "degreeing the...
Hey guys,
Finally getting around to checking out a motor I picked up that supposedly had been rebuilt recently. Piston bore looks good with no ridge and installer had put in a .20/.20 crank. Also getting ready to degree the cam to see what is in there.
The crank and bearings looked good. I...
Hey Earl just going off of what was said way, WAY back on the fillets on the turbo Regal cranks and not going past .010 for strength. I'll drive the thing with .020 bearings and not think twice until it either wears out or blows up!!
Hey Mike thanks for the tip I'll get a degree wheel and check it out. I have to call or e-mail you and ask some tech questions/get some recommendations.
Hey there,
Getting back into the GN game after a long break... I've got a used engine I'm tearing apart to take a look at and might use short-term to get my car running again until I put together another engine I've needed to assemble for a while.
The used engine has .030 pistons (with no...
Hey there,
If you still have the $800 rebuilt 86-87 3.8 turbo short block, I'm interested. I tried to send a PM but can't figure it out!! I just have a few questions about it.
Thanks,
