See? I can do it too

Seriously though...people on this site can be ridiculous sometimes. Everyone is so quick to hop on the AFR bandwagon that they ignore a little detail every single time- TW's and 165's are pretty much equal, and if anything the wedges outflow the 165s. People can't seem to get this through their heads, no matter how many threads we have discussing it... Now compare both of those after porting, and the AFRs get blown out of the water. Not to mention that the TFs are still a good bit cheaper.

if you dont want to get into the whole porting argument then i would say afr's

what about edelbrock performer RPM heads with 2.02 intake valves?

In one of the Head chart comparrisons i have it shows the AFRs outflowing the Trickflows by a lot on the exhaust side, which is why i'm guessing the AFRs usually make more power than the TFTW even though the intake numbers are very similar. My dad has a set of TFTW heads and I have AFR 165s, we put them side by side and after looking at the ports its pretty easy to see why the AFRs cost more. From what ive seen online the AFRs usually make more power than the Trickflows regardless of what the charts say.

also keep in mind that between the twisted wedge and 165s, the tw have bigger intake valves. 2.02 vs 1.9

i bought my 165s because the tech dude i was talking to at afr recommended it over its higher flow bretheren.

link for you nooblets out there(damn, i feel sorry for you folk running stock heads)

dthompson67

which is better with no porting done to them? if any to get them to match gasket or the victor jr intake?

ooticamitica

afr's are better but the tf kit is good, of course you can make better by mix matching good parts w/ a custom cam.

dthompson67

ok tell me which would be better and whats the hp estimates

holley 650 doubple pumper
victor jr intake
trick flow heads (not ported) or would i need to do somet port work to get the to run right?
.512 custom ground cam (do i need a bigger one)
.40 over flatop stock style pistons

let me know and then how would it be if the heads were afrs?

I like them both but DSS told me to go with AFRs. With your set up I would either get the CNC ported Trick Flows or the 185 AFRs. They will be close in price and are both excellent choices. Be careful with the stock style pistons and 2.02 valves. A custom cam would be better that way it can be ground with the proper timing needed to clear.

dthompson67

ok what would be some good pistons. cam and heads that will all match good and be fairly under 1300 or so. forged aluminum pistons and stuff? let me know what would be good and the hp estimate
