I have recently purchased a 351C 2 bbl V8 2 bolt main. Still in running condition. I have been told that for the street.This would be a better block then the 351 C 4bbl 4bolt main. If so..and money was no object. How much horsepower can I expect to get out of it..properly machine and put together, with out blowing it to smithereens. Since this V8 will be in a vehicle with a automatic, and 3:50 rearend, quickness is what I am after. Thought I should mention that this V8 May be in a chevy, thus the name ChevFord..

For street use, the 2V block is fine....IIRC, there were 2 bolt 4V blocks as well, with the Boss 351's having the 4 bolt blocks...I don't remember for sure if the HO blocks were 4 bolt or not...I think they were.

A well-prepped 2V engine should be good for 550 hp or so with an automatic trans...

2V block better? I'd say less expensive but not better...

There isn't as much strength difference between a Ford 2 bolt and 4 bolt main setup as there is with a small block Chevy. The 2 bolt main Chevys are very weak compared to the 4 bolt versions. I ran a 302 with a 2 bolt main block at mid 11's in the 1/4 with no problems.

But like Pat said, 4 bolts are better if you can find/afford one. They're just not as necessary with a Ford as they are with a Chevy.
