afr vs dart

**silverz28camaro** · 07-31-2007, 08:35 PM

the price is my biggest concern , the afr is near $2200, and darts are around 1600 from summit and have 62cc combustion chamber over the afr 65 cc chamber , the afr are proven for 40 horse on a stock ls1, but i cannot find a dyno run on a dart head swap, but i can't see why the dart heads wouldn't create just as much power or even more with the smaller chamber

afr 205 if you gonna get a good cam and Fast 90/ TB 90 with that... maximize air flow...
if you do LS6 intake and ported stock TB then no need for AFR heads since your intake will be a bit restrictive anyways... it's your call... I assume you have full exhaust in mind too. LT H and Y and cutback...?

AFR's worth the extra money in my opinion.

I bought Darts when they first came out because they were a good deal and there was a pretty big difference in cost between them and the AFR's at that point in time (I was actually saving for the AFR's when I bought the Darts). I got decent results from them with a small cam (24 hp). My next upgrade (over next winter) will be from the Darts to the AFR's with some "special" tweaking on the AFR's. Its really a trade of power vs. dollars. I believe the Darts are very good heads for a price point, but they won't keep up with the AFR's from a pure power standpoint. So if you have the money get the AFR's would be my recommendation, if not the Darts are good heads based on my experience but you definitely won't get as much power from them either. AFR's will likely fatten up the mid-range power more as well as the peak numbers.
