questions about 71 454
I picked up a basket case 71 coupe some time ago and have slowly been getting it back together. Never having done this before, it's been quite a challenge. My major problem now is figuring out what to do with the engine. One of the previous owners had it bored out 30 thousands and put 11 to 1
high dome pistons in it. It has a torker 11 manifold and a holly 750cfm
double pumper. Whoever did the machine work or assembly didn't get it quite right and the pistons were just barely kissing the heads. Now for the
questions:
1: in 71 when they detuned the engine and brought it down to 8.5 to1 compression how was this accomplished?
2: Did the 70 run the high dome piston.
3: are the 70 and 71 heads the same.
4: is there a better intake and and carb out there that will fit under the hood
( I understand thru reading this forum that this isn't really a great setup for this particular engine).
I would like to rebuild this engine as just a mild performer that I can run
with pump gas. All suggestions and question answears will be greatly appreciated. Thanks!

Re: questions about 71 454 (Tom73)
Torker II is your only choice for oval port intake that fits under the stock hood. I tried to make my LS5 run right for a long time with that POS manifold. Finally gave up and got a high-rise EFI setup and a L88 hood and it's all smiles now.
