Default Best way to lower ET

Ok, so I'm selling my 1972 Mach 1, and will have about 6500 dollars to put towards something. This "something" will be my 98 gt auto. At first I was going to fix up the 2v with heads, have them p/p and get some cams, but then I figured that it might be better to go with a 4v swap from a 03 Mach. I want everyone's advice on what I should do. What I do know is that I would like between 350-400 horsepower, and would like to run in the low 12's or high 11's.

If this was your guys' car, and money, what would be the best way to get this out of my gt?

If you want to run 11s with 350-400 WHP, sticky tires and suspension work are going to be a must. With say 375 WHP your going to need sub 1.7s on the 60' to break into the 11s.

IMO that means your going to need a rearend rebuild to make it reliable enough to do more than once.

So far as power, your not going to get there (350-400) without either lots and lots of money in the engine (lots) or n20/blower on a 2v app. A 4v could make this with the right combonation but its also going to be pretty expensive.

If you are willing to trade some ET for MPH, you could go with a lower HP number, and setup the car with running slicks in mind. With less power, more gear, and the slicks, plus the right suspension setup you could run 11s with alot less power but better 60' time. Get it down into the 1.5 range and you won't need anywhere near 350 WHP to go 11s.

Get the Driver mod... lol! Nah man i agree with 2000gt4.6. Blower, built rear end, slicks,suspension,and pray your tranny holds together. Ahh just screw it spray the hell out of it. It would be the cheapest way to get in the 11's!

Drag radials, Rear end, and the mach engine would be a killer setup. Don't forget the clutch.

without swaping the motor or building it, do a pi swap, throw a blower on there or nitrous. lets say u can get 400rwhp out of it with a blower or nitrous. you will need a nice suspension set up(shocks/struts, springs,SFC, upper and lower controle arms) throw some gears in it, built the rear cause ur most likly gona need some slicks and if not then just sticky tires in general. and on top of that full bolt ons and youll b good for some high 11s..maybe 11.7s. just a guess

I will say that I'm not really a fan of FI, I know that sounds retarded since I said ~400hp, but that's why I was leaning more toward the engine swap route.

If you're not into FI too much a 4v swap, 100-125 shot, good tires and some driving talent will net you your high 11 fairly easily.

that's good to know. I think the 4v is what I'm going to do. Will there be any problems with the motor/bellhousing/tranny all bolting up nicely? Also, if i get shorty headers for the 4v, will they bolt up to o/r x on my gt?

If there is anything else that I need to know, any input would be greatly appreciated
