If your going to drag race a C3 Vette you want to go a lot stiffer rear spring then 360. Start thinking 500 to stop squatting.

On the Corvette forum C3 tech. There is a guy ( motor head ) has an 80 same hood with a 427 SBC victor JR, demon carb.

Back before bracket racing lots of weight to cubic inch. A lighter car always a plus, I always wonder why when drag racing why so many people use a heavy pig of a car to do it.

So what do you do now for kicks. Buy an aftermarket 4.60 bore block and drop the 348 W crank in it. Lol

Back when pro stock was weight to cubic inch. I wonder how well Reher Morison I think it ended up 368 cu. BBC did when they dropped in a 3.25 stroke 348 W crankshaft into a 427 block.

The gen 1 chevy common as dirt on the ground, the bbc just about as bad to many. The LS engine so many swapped in old cars there now way to common. To me not done much anymore a 392 hemi built to look like the 60s top fuel engines great looking, my second choice would be a 409. If power not a driver...

Ya the springs were a bit stiffer for valve weight. The old 30/30 cam that was in my 69 Z28 sbc was
485 lift using a 1.5 rocker. A 396/375 or the 427 solid lift bbc only had
.520 lift using a 1.7 rocker. So the bbc with its bigger base circle cam, tbe cam itself was milder in lobe lift.

I would assume the 1.7 ratio rocker along with the slightly stiffer needed valve springs for the heavy valves( compared to sbc ) then lifters pushing on pushrods angled out of them at 4 degrees, all contributing to more cam failure problems then sbc.

I just know in not to disdant future im going to have to find a machine shop in DFW tx. To do it, its an old factory block.

What kind of a machine what is it called that a machine shop would have to make lifter bores right BBC.

Do you need anything else off/with it other than the bare block. In a PM tell me what machine work you can do, cost on each type and what your guess is it will need. One way or the other i have to have good machine work done. Only thing i know for sure would want at least .060 over bore. I assume y...

The only runing 400 i saw was in a 70 monte carlo, freind of mine had a 400 block back in 70s i had a large journal 327 forged crank i had used in a 331 build. I gave it to him we built the engine in a shop we shared the rent on. He put it in his 69 camaro i had a 66 vert vette at the time. We put a...
