Subject: Re: Driving impressions with the AFR heads by Steve40th on 2009/8/19 6:06:34 AFR heads are no doubt great. My only problems with all these threads, that get heated, is there is no real data. A simple test would be dyno these heads on a engine dyno, using same throttle body, compression, cam, manifold and tuning. That being said, all these heads are different and require different cams, compression, manifolds and throttle bodies etc to perform at there design level. My 396 LT1 runs 119 mph consitently, well prior to the track closing. It has old LT1 heads cnc ported by a company CNC prom Florida. I use LT 1 3/4 headers, Vigilante 2800 converter, 3.75 gears, and MT ET streets and shift at 6500 manually second to third only. My cam, off the shelf 230/236 112+2 LSA and 544in 555 ex. Standard street engine, to an extent. So, If I could get AFR's, I need a new manifold? Heads angle milled to meet my 11to1 comp, a new camshaft to match the head, and a retune. Maybe even change my 12 year old Flowmaster cat back. SOrry to babble, but there is more to a fast and quick car than heads. Its a package! |
