The current set-up in my 347 was set up for street/strip usage in a 1990 Mustang Vert.

Now that the motor will be used strictly for drag racing, I'm wondering if I should change out a few things.

The engine is on the stand now and will soon be dropped in the '70 Maverick.

Current system:
1) Cam =.224/.232 @.05, .510/.534 w/1.6 on 110 > deg. (*see SRP pistons for valve clearance)

2) Injectors = 24lbs (matched flow)

3) Heads = AFR 185, 58cc chamber, Intake Valve=2.02", 1.60" Exhaust, Ported Exhaust (for nitrous)

4) Fuel System: Aeromotive's A1000 Fuel Pump, P/N 11101

5) 4340 Crank

6) 4340 Hbeam Rods

7) SRP Forged Pistons (-5cc dome volume)

8) Stock block is internally balanced, girdled, align honed

9) Cobra upper and lower (ported, gasket matched, etc).

10) Stock Block: Line Honed, Zero decked

11) 1-7/8" Long Tubes with 2-1/2" off-road X-pipe

12) Crankcase evacuation system (early 90's Ford truck smog pump - which I don't recommend)

13) Cold air, Pro-M 77mm(?? brain frat)


The engine (and 175 shot) pushed the Vert to a best of 7.02" @ 101.XX mph in the 1/8th with a 1.5X 60' using the more restrictive (than AFR) Windsor Jr. Heads on 28" ET Drags.

The engine was great for street/strip (idled well, good throttle response, no overheating, etc) but I'm willing to lose a few things to get a few more horses on motor. (I'm limiting the combined enigine and nitrous shot to 600 h.p. - I don't want to approach the limit of the stock block (~700 h.p.?)


The tranny was AOD (std gear ratios) with 2800-3200 stall (flashed higher) converter.

The 8.8" rear was a 456:1


Maverick Specs:

Weight = ~ 3,000 lbs (max) with driver (vs ??lbs vert)
The 9" rear currently has 4.11:1 posi (locker)
Tranny = C4 w/ 2800-3200 9" converter
Tires = 28" X 10.5"


I'm pretty sure the existing setup would push the much lighter Maverick a little quicker than the Vert.

Delima: Do I stay with what I know works well, or do I make a few changes while the engine is out (cam, injectors, gears, intake, etc?)

Your suggestions/comments are appreciated.

Thanks,

Rick

Could you swing some 4:56's for the 9 inch? 700 HP is some serious ponies. I'd like to see it run or at least some results.

Jerry: Nice but you didn't have to do that, if you ever get it going fast enough at the strip it'll catch fire.

I have a video but can't seem to get the link to work right.

It was a run that I had a shi**y 60'and ran a mid 7 at 90+ mph. I won't be running 700 h.p.'s. I hear the block will only take a dozen or so runs at that level. I'm keeping it to 600 (but have the jets to get there $hould the right race come along ).

Re: "I'd like to see it run.."
Although the following video is of the Mustang that the engine came out of, you can "see it run". I'm hoping for much better numbers when it goes into the Maverick.

Try to copy and paste (or moderator can edit my post to link directly to it??) :

Let me know if there's a problem viewing it.
