Thanks for the info. I don't doubt AFR quality. I'm sure they flow great. One head offering can't be all things to all people. I'm just trying to figure out if they are right for my set up. I've got a quality H/C set up, and if I'm investing a good chunk of change, I expect a significant upgrade. I feel bad for the guy who added AFRs, 90 mm LSX manifold/TB and picked up 20 hp.

 

The only problem I can see happening is that all these big Cam only guy's will neeed to cut there pistons to run a decent compression with the AFR's..I would rather see smaller chambers without milling

 

Sounds resonable. Hey, this is the best consumer advisory board available. My company pays big $ for this kind of input.

 

You mean the guy that bolted on AFR's and removed fully CNC ported heads (not stock) and made 20 more HP with a full point LESS compression? That guy should be a happy with his results all things considered....another 15-20 HP is just an .040 mill away!!!!

Check that thread if you want to see a more detailed response I made concerning that situation.

Mr. Max....Call me at AFR if you get a chance....Would like a chance to earn your business.

That's exactly what I'm getting at. It's going to be kind of hard for me to get the compression I want while still running on pump gas and not having to go to a dome piston.




The same goes when you mill the heads. What about when you mill the heads .100 to get the correct compression? How is that going to affect the valve train geometry?

 

me too

 

so i came out with 435. even if u added 20hp thats 455. a far cry from your 470 plus and i have a bigger cam!!!!!
guess i should be happy

 

ttt

 

keep in mind you PP numberes were low too, i wouldnt expect to gain 55rwhp with with lower compression and the additioin of a slightly better intake/tb combo.

 

Any new or updated info on the Edelbrock head?? What do you know or what have you heard?
