Re: chevy 250 3 barrel holley

Talked with Tom personally about it, and it works good. In that wagon he has, last road trip he took it on he got something like 24 miles to the gallon at 75 miles an hour with him and his family; plus a bunch of stuff in the back.

Re: chevy 250 3 barrel holley

The proof is in the driving. That 250(?) six really turns on compared to a Monojet. I have been driving a six cyl Camaro for many years off and on and it doesn't turn on and rev like that. Apparently the heads can handle some more air flow. I think it's a great mod

That 250 has alot of internal mods as well. Yes, you can lump port the head and install bigger valves for a Nice increase in air flow. A higher lift cam really is the icing on the cake though.

Ah ok, I thought that's what he meant when he said a little extra tuning will be required. Be sure to let us know how this turns out!
