i'm scratching my head wondering why you guys think losing 20-30 cfm through the manifold are good numbers?




Dan this intake was not even gasket matched. Every intake I have tested has picked up 10+ cfm just by doing that. Flow a small block super victor sometime if you really want to see a piece of crap. I bolted a small block chevy victor jr. to a set of Dart platinum heads I ported and the numbers dropped from 300cfm to 260 and the chevy guys love that intake.




okay, i see what your saying. the ld340 is better than some of the other intakes. i'll buy that. the ports in that manifold are tiny, so velocity is high, but the flow still stinks IMO, even after gasket matching. for the right combo there'd be an obvious gain over stock, but that intake will only get you just so much.
glad you flowed it and alway's enjoy seeing results like the ones you posted.
