383 LE2 dyno #'s I finally got the car tuned by Bryan Herter today.
He found some power over the mail order tune by leaning it out and playing with the timing.
424 max RWHP SAE and 472 RWTQ (converter flash).
It made 434 RWHP std.
Base run with un touched mail order tune was 413 RWHP.
383, LE2 heads, LE2 cam, ported intake 58 MM TB, Delphi 37 lb inj, KOOKS headers, 3" true duals, A4, Yank 3200 stall, 3.42 gears, 17" WS6 wheels.
Bryan mentioned the plugs need to be changed and it had a "bang" at high RPM after being ran on the mail order tune with low timing for a while. The abuse the plugs are being put through is showing how bad they are. He feels that new plugs will fix it so a new set goes in next week.
He "estimated" the #'s would have been about 20 RWHP better for a 6 speed car and a new set of plugs might gain a couple of HP also.
As "ALWAYS" there is more in it but the only thing that matters is what the dyno and track times are. we all have the "woulda, coulda, shoulda" about their track times and dyno #'s, lol so i'll just have to live with these #'s.

Great numbers Lloyd. I see you are running 37 lb injectors. Do you think my 30lb SVO's might be holding me back. I am working with Bryan as we speak on my tunning issues.

that was locked but the converter would not lock until a higher RPM and the converter flash was always there. Unlocked was 407 i believe.
I have Autolite 104 plugs in there and will be going back with a new set of them.
It went 11.55-11.53 in the 1/4 at 117 MPH and 7.30-7.35 at 93 MPH in the 1/8 last year. That was using . . . . .
base mail order tune
stock 82K trans (sluggish shifts and very mush lock up at track)
17" front and rea wheels wit 17" DR's (1.59-1.63 60 fts with a lil spin)
3.42 gears in stock 7.5 rear end.
Improvements this year are . . . . .
Bryans dyno tune
CPT trans (MUCH firmer shifts and quicker lock up)
15" WELD 15x3.5 and 15x10 with 27x11.5x15 Hoosier QTPs (should not spin)
3.55 gears in 8.8 ford rear end
I am hoping to see 1.5-2.0 tenths from all of this with the light wheels and 8.8 rear end will off set each other and the improvemets will be from tuning and new trans.
Maybe some 11.30's at 119 MPH and 7.10's at 95 MPH in good weather. We'll see.
Getting the car set up for nitrous later in the year otherwise I would have never swapped rears.
I have the graphs in my email if someone can post em for me.

Awesome that is exactly what I'm building only no duals and I have a 6-spd. I did go with a electric water pump and some stepped kooks headers so I should be able to match that number, I hope anyway.

probably so. I have had customers make over 450 RWHP with a 6 speed.
A4 and stalls just jack up the HP #'s at the dyno but are better for track times.
Schweet97 . . . Dyno graphs are on the way. . . . thanks.

lloyd i was just looking over your heads and cam combo, but what is the reasoning for your choice of the ur stage 2 heads and cam? y not go bigger on the cam and do more work to the heads?

I was swamped with work (as usual) at the time of the build so I bought some of my used heads, cam and ported intake from the for sale section. they are some that I did about 2 years ago. If I was to have done the work, it would have been LE3 heads and LE3 cam. The LE4 cam would be a lil much for the 3.42 gears and the drivability I am after.
I would love to have my current LE3 heads, LE3 cam and intake ported the way we do them now in this car. I would LOVE to have some of my newer stuff on there but I am not tearing back into it for 10-20 HP . . . . I'll just run a nitrouis pill 25 HP bigger and call it good, LOL.

My set up with your heads did 460 locked, even with a 12 bolt (12 hp loss verified on dyno) so there is always more to be had Lloyd....
Hopefully this time next month I would have run 11.1-11.2's full weight---plus roll bar on your ported AFR heads...
