302 upgrade decisions

Need some help with my 88 SO 5.0

Currently is all stock with 113K.  My goal is mostly driver with good performance, must have ALOT of torque and stock drivability.

I have most pieces for the HO upgrade, but E7 heads,

Do I  1. Use SO block and put on E7 heads (stock Mustang headers)  Do I do some home porting on the heads? Will this benefit with the stock HO cam?  Do I do any porting of the HO intakes? Again, will this benefit with the HO cam?

(I will be swapping to a 2.5" offroad H-pipe and some aftermarket lers also.)

Do I  2.  Buy a used 5.0 HO motor (notched forged pistons) and upgrade the heads to GT40/GT40P along with Cobra/Explorer intakes?

Should I spend money on shorty headers, or use the stock Mustang?

I guess it comes down to......what is the most torque/dollar way to go?  I plan on keeping this car for a long time and dont antite forced induction any time soon. LOL, but I would like to do it right the first time.

I plan on eventually going to 3.27 or 3.45 gears in the 7.5 rear.

I know this thread is long, I just need some advise from you guys who have done this before with these cars.  Thank you

Mike

Option 2 will get you more power but you will not be able to easily use stock HO headers with GT40P heads. The plug angle is different on them. Trust me I know ;)

I guess I was asking if I use E7's, would aftermarket shorty headers make much of a difference?

I know GT40P's require a little different setup.

I would get the e7's. They cost the same as a stock head at a junkyard. And almost if not all headers will fit it okay as long as you have a floor shift. The stock mustang headers will work fine with a colum shift. at the u-pull it yards around here, a set of heads is 40 to 75 dollars each, and a full motor is 125 to 150. With the H.O. upper cam and fuel injectors, you'll prolly be cheaper with the hole motor.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

Will the stock HO cam allow enough airflow to justify a more expensive setup? (cobra intakes/gt40 heads)

Your motor is a big air pump. Lowering restrictions will gain you more power. The stock upper/lower is the worst flowing part of the H.O. setup.

You could always go for a different cam. They can be found used for a decent price.

You can find CAI's (cold air induction) pretty cheap if you look around.
