As usual, our manifold pickers got carried away, mistaking a B for an RB. The Street Dominator may be really good on the RB, but it doesn't show so well on the B engine, like yours. The Perf RPM is enough better that you should be looking for that. The Torker 383 is a really good intake, especially for an engine quite a bit larger than a 383, and I got mine for $50 at a swapmeet.

I will try the Perf RPM I hope gain Mph...
Thanks
