Re: My Trickflow #'s

Those are nice #'s. These new Trickflows will help us LT1 guys with an affordable aftermarket head that flows nicely. You can buy a new pair from Summit for $800 with the $100 savings they have on them. I should get mine back from Lloyd today with very similar numbers. Later Clint

Re: My Trickflow #'s

I think the intake ended up being 205cc.

I had a local machine shop do them.

Re: My Trickflow #'s

Nice numbers, that's almost symetrical port ford territory with a 205cc runner.
