You want torque at low RPM, how's this grab you? Again, the TrickFlow 235's are on a 4.187" bore in this case. The engine feels like a diesel at low speed. Again, this is on pump gas and street tires with the A/C hooked up.

for what its worth, i wouldnt say im upset you wouldnt warrenty them, im more upset you said you would, i told you they where worked and welded and then i ended up getting the shaft and the shipping back in my face.

again, im not an afr guy and everyone i have spoken to about afr's seem to think they are over rated and for the $$ you can get better.
good luck either way

If you are watching $$ then you will not be disappointed with patriots...

We made 535 rwhp NA with a set of patriots and a 238* cam on a 408.. That was almost 2 years ago and that car is still running strong.

If you have the extra cash then the TFS heads are definitely a kick *** option too...

You will be impressed with either head!

Here is the post of that patriot head car..

It makes torque too..

This is another setup with same heads and cam as above but stock 6.0 shortblock.
