I'd run my car if I could, but our dragstrip in St.Louis closed this year so I'm out of luck. I built the car to run it and drive it on the street.

Build setup:

Suspension -

Moog V6 front springs
Moog 635 springs in the rear
Lakewood 90/10 front struts
Competition Engineering rears
BMR adjustable panhard bar
BMR subframe connectors
BMR Race Adjustable Control Arms and relocation brackets
BMR Full length torque arm

Motor/tranny/rear -

355; 10.2:1 compression
Dart 200CC Iron Eagle heads with 1.6 harland sharp roller rockers
Comp XE274 (flat tappet)
Edelbrock Airgap RPM
Quickfuel 750 Annular (mechanical secondaries)
Hedman Longtubes dumped with Borla XR-1's
TH350 with a Hughes 2500 lockup converter (this will change soon when a new cam goes in that I grabbed from Crower.. new cam is 240/244@50 with 490/490 lift with 1.5's ... will be using a 3500 stall converter)
3.42 gears


Outside of my gears, EVERYTHING is literally brand new. This is my first street/strip build, but I doubt I'll be able to see real numbers anytime soon. What do you guys think it'd run?

I'm going to say mid to low 13's first time out till you get things dialed in.

What's a build like this capable of, you think? I've seen plenty of HP/weight calculators, but I don't feel those really count because it doesn't take into account of suspension optimization (unless it's assuming a PERFECT run, then I could see a static ratio being in there).

You can't ever count the calculators that use your ET to calculate HP. Its way too dependant on the launch. The only ones I'd use would be those that use trap speed and vehicle weight.

If those heads flow like what I saw on darts site, and you have a cam to match them I'd say bottom 13's all day long on street tires with an average launch.

My GTA with a B-body LT1 making 260hp + bolt-ons goes 13.3 @ 103. This is on 10 year old kuhmo supra tires, they are hard as a rock. The stock iron LT1 heads don't flow near those iron heads, and the cam is ridiculously small.

My set up is a bit different than yours. I have a bit(little) more motor than you but you have long tube vs my shorties and you have more suspension and chassis work done. I ran a 13.3 at gateway but my timing and carb was a bit off and I didn't have my exhaust dump on then. I got those things nailed down now and would like to get in the high 12s.

Gateway is opening back up so you will find out what it runs soon enough.

gateway is the track NHRA runs at for the st. louis nationals race is it not?

Sorry to thread jack, but I'm curious what mine would run if the tranny wasnt being stupid (aka dying). I have an iroc with sfc's n a strut tower brace, moog 5664's and 5665's. 700r4. 3.23 posi rear. motor is a 355, with flat tops n 64cc heads, block was decked too. 420/442 cam. 1.60/2.02 heads. 600cfm carb. Shorty headers into true duals. If you need anything else to make an educated guess let me kno.
