Thunder Racing has a new cam (247/251 .624/.632 112 LSA) for the 383 and with a set of 225 trickflows a guy cranked out 537rwhp and 488rwtq on a Mustang dyno.

Holy Fark that is alot ! Mustang dynos ARE more easily manipulated than dynojets but either way I would LOVE those numbers !!

ETP has been out of business for a while now and Cary started a new company (Performance Induction) which updated the ETP design. They are best LS1 head on the market IMO and sell for about $2800 with rocker stands IIRC. TFS, AFR and the TSP proprietary 215's are also nice. Not a fan of ported stock castings.

FAST no longer makes a 90 or 92mm Intake but only the 102. You can put a 90/92mm TB on it though....

This! Definitely PI.

I don't dislike a properly ported and milled set of 243s. I have had some big numbers come from them, but nothing like the aftermarket castings obviously.
