Trick Flow small block heads
Well there was a guy on the forum bout a month ago that wanted to build a 10 second street car. We talked about how unrealistic it is to build a 10 second car safely. Garret's post reflected on his current build and what is truly involved with the car structurally and what it realistically was costing. He talked the guy into staying with a 12 second car instead. But it was the way he wrote the post that was very good. Another good post that someone made was how flow numbers can be deceptive to the real performance expectation.
That is what Yellow rose is trying to explain to you.
Any head that uses offset intake rockers, w2,w5,Indy 360-1&2,
Edelbrock Victor etc will perform in a much higher performance level
Than any stock rocker location head, regardless of its advertised flow numbers, because the physical port size is made bigger.
You cannot change those physics.
It's important for you to decide on a realistic performance goal to avoid spending where it will not help enough versus the dollars spend.
