I will have to admit I do have one Chevy in the fleet,it belonged to my great uncle and if I did not take it it would have been made into washing machines or other metal products by now,the 235 six I rebuilt has a rod knocking so even though I have a couple extra 235s I am seriously thinking about dropping a 302 and c-4 down in it. I am going to pull the 235 out in a few weeks and do have a 351-C that I will measure to see how it wil fit but thinking a 289/302 might be a better fit sinced it has a very narrow engine compartment.
