Hi all,
I just joined.

I bought a 67 Impala sport sedan without motor and trans a few days ago.

So the car will never be a numbers matching car. I want to build it to enjoy using it.

I have been searching for a big block 427 or 454 engine which I can rebuild and have not had much finding one.

The one I have found, is apparently a 1973 dated 454 2 bolt main 289 casting block and I have been told it has a TRH suffix code. The seller thinks the block is out of a truck originally.

The heads are 122cc #049 heads.

I would build it with a Thumper or Mutha thumper cam, the highest compression pistons that I can still run with 91 Octane and 2.19/1.88 valves. I can go with any other mods like higher ratio rockers if so advised.

The car will be for road use and that too, not for motor way use. We have no motor ways here in Sri Lanka.

Hard acceleration is what I'm interested in and a killer idle like this

What sort of BHP could be expected from such a build ?
Is there any "shame" in using a truck block in a car (of this nature) ??

What pistons would I use ? car or truck ?
