I have these out of the box (except springs) on a 4.125 bore 427 that I built at home. 10.5:1 compression on pump gas and it made 650hp. Pretty decent for heads I walked in the door and bought at Summit.

Great job explaining what you have, even those stock small fords rev quickly and run hard...

For the guys who doubt if anyone runs a 1 inch valve lift on a SBF.. look up revan evan's video on the 10, 000 rpm maverick that makes 1050 hp all motor.

How do these compare to the old school 225’s ?

Eric have/will you ever do some SBF TFS 11R testing?

I know my headers are on my floorboard right now, I’m curious on how they’re gonna fit when I bolt those Promaxx heads on.

Any recent porting #'s/info on sbf 20° Brodix track 1's raised runner heads? I got a set of 225cc wanting to send them out to get max ported for a 434-440ci combo I'm putting together.
The Afr's are great heads I had the 205 renegades on my 363ci 630fwhp at 10.9:1cr.

When is the LS vs SBC boost video coming out?

[petemcpeterson]

How about the s10 track day video? We all been waiting for that one .

[haydenjordan]

according to their website the promaxx shocker 210 sbf head seems very comparable

Past .700" on the intakes, they blow my Chevy 220 cc Eliminator Competition Ports out of the water.

Do you think that a 2.100 is the biggest you'd stay on these. Or could you increase to a 2.125 and leve the 1.57 exhaust?
