That's a great picture of your parents with the '53.

Yeah, but with auto trans, not too much.
The Crane hydraulic roller I used in the El Camino and still have in my 49 Studebaker dump truck idled dead smooth; but it was a torque monstor. Used Morel lifters and stock Chevy valvle springs. I know I have the part number some where.

OK, I also have a 200-4R trans. Not clue if it will match to a PG.

I know it seems nuts to even consider a trans swap, but I am seriously considering going with a 4L60E when I install the dual quad engine.
Don't have to cut one thing to do it other than the driveshaft (and i can always pick up a used drive shaft to cut down) and can always save the PG in case someone wants to go back original. That OD trans with a lock up converter would work great with the current 3.55 screw.

200 4R is a direct replacement for the PG/TH350, no driveshaft cutting, just move the crossmember back, which I'm rather certain you need to do for the 4L60 too. The 4L is also based on the old TH400/700 r4 and has the larger case. Are people able to install that in the tri-five tunnel without cutting/modification ? I know the cast iron PG I removed from '54 was quite beefy and may have been larger than the aluminum case ones ??
My 200 is built for 450 hp 500 torque, there isn't anything that little 283 is going to do to hurt one built right.

A rear transmission mount and crossmember would be needed. Don't know about the strength of the front of the transmission case with the front engine mounts being so far forward though.

There is a kit available for mounting the trans to the original location using bell housing bolts, and it takes all the stress off the bell housing.
Yes, the 4L60E fits just fine. There is a LOT of room; way more than there was in the El Camino. And I didn't even need to ding the floor to install that one. Just need a shorter drive shaft. Would definitely consider a 200 4R, if I found one for a decent price. Because it IS a direct fit on all the 50s 60s and even 70s cars, they are getting scarce and more expensive. Regardless, any such nonsense is down the road a ways. I need to get back to work on the LT-1. Keep getting distracted.

Agree, they are getting more difficult find.
NOW, get to work on the 'vette...  I have been distracted from the Camaro for some time too, but have been making slow progress on prepping the doors and fenders.
