Default Crockett Marine Small Block

THIS IS A 434CI 9.4 TO 1 that runs on 91 octane pump gas. We built 2 of these for Furniture Row Nascar Team going in their 32 Sunsation.

We used the SB2 Nascar heads that they do not use because Nascar went to the RO7 engine. I had a 650 lift cam ground on a 112 center and used the FAST fuel injection. I started with a Dart block with a .325 raised deck and a .391 raised camshaft and had Dart machine the SB2 lifter bore spacing in the block. We welded the injector bosses into the stock Nascar intake and used a 2000cfm throttlebody. Winburg made our 4.000 stroke crankshafts and we used the 6.200 long rods they ran in their car engines. I lowered the compression to 9.4 so we can run on 91 octane fuel.

How much weight do you save over a big block?

Ok Sounds great, Weight savings, Great HP. What is the down side? If you have enough torque you should be able to spin the same props as a Big block. Help educate me. In my limited knowledge I do not see a down side. Why would you not run a small block? Maybe the CG woould be off? But I would think if you build it from the start then you can set ip up for the small block. Heck I spin my big block to 6,000 anyway.
