Remember you only have a mouse motor up against a Chevy big block LOL I went from Mouse motor to a fuel injected 427 Chevy then I also switch it out to a tunnel ram with two 1150 holly strip dominators on there plumbed with nitrous in my 56 Chevy but I had a better time when it was hilborn fuel injected I was running 1101 it was a street legal Gasser sat too high to get me into the tens
