guys,wow what a hassle, if i only had the knowledge i have now back when i started this project i am sure i would not have started it.ended up with 12.4 to 1 compression in a 900 mmr short block trick flow heads 38cc stage one port, cams custom grinds thru modular head shop [bullet cams]. at .050, 250 /245 duration 550/545 total lift 111 lsa 107 centerline. adapter plates port matched to intake and heads. Intake is a victor jr. trottle body plentom is sulivan and a cobra twin 64 i have a one inch perameter n/x spay plate -6 feed line and two 10lb bottles in the trunk. had to go with ford racing shortys.i have a 4stbe manual shift valve body transmission with a pi coverter,cant lock it up on the dyno.Put up some lowsy numbers.My est. drive train loss i believe is 25 to 30 percent. 319 hp 350 ftlbs of tork, flat lined at 7200 than broke up. On the bottle 490 and 575. i need to make some changes. need to put a logan on it and long tubes but ran out of money! dont know what it will do at the strip yet, blew a head gasket had to drop the motor be back together next week.

An unlocked converter losing 20% up top compared to a locked needs to be thrown in the scrap pile. I did a test with Stafford's 4000 stall and we lost ~10RWHP on a ~290RWHP NA motor locked vs unlocked.
IMHO the intake is choking this motor, I don't think it has enough plenum volume for a 5.4 as it sure doesn't have enough for a 4.6 even. Here is what a proper 5.4 Victor style intake should look like and even this one is smallish plenum sized (we made it as big as possible though given the space constraints):
And here is what he really needs if the wallet will allow it, notice the plenum is nearly double the volume:

Beauty here is not just skin deep, its even more beautiful on the inside:
Those sheetmetal trumpets are mega expensive to fabricate and are the most important part this design. Since its all thin aluminum it doesn't heat soak like a thick cast intake does. However its noisy as hell.
