gt40p combo

[MustangMulch]

My plan is to add an SC-trim later on down the line, but first i was thinking of adding this:

GT40p's
TFS street heat intake
TFS stage 1 cam
accufab TB (65mm or 70mm.. not sure)
and of course at some point i'll add 30# injectors and a AFPR. Should I do that with the h/c/i, or will it be ok to run the stock injectors until i get the blower?

How much power can I expect with just these things, and the mods in my sig? How about after the blower?

Also, with that combo, will I be able to add a blower pulley and run maybe 8-10 lbs of boost? Or what would I need to do to run more boost without hurting the engine? "Supposedly" my engine is bored .030 over to a 306, according to the guy I bought my car from a year ago. But i don't know how true that is. So let's just assume I have a stock 302. It has 47k miles on it right now.

can anyone take a stab at it?

With the GT40p's and their 59cc combustion chamber, I would recommend not running more than 5-6lbs. The compression ratio will be to high causing deadly pre-detonation to your motor. Either go with a head with larger combustion chambers(gt40's) or go with a lower compression piston.

Any more opinions?

You will also need "P" specific headers for the GT-40P heads, which you probabaly already knew.
I am guessing you will probably get about 50 hp out of those 4 mods. Someone correct me if i am off.
I am also doing the P heads with a GT-40 intake so any more opinions would be appreciated

59cc should get you close to 9.5:1 (w/ stock pistons). Cut 0.030" off the bottom and you're close to 10:1 (w/ stock pistons). Either way he'll be fine running 8-10 lbs, back the timing down to stock 10 degrees of cousre.

Yeah i was aware that the P's need special headers, but what about other heads? My original plan was to get some Twisted Wedges. Can you use any longtube or shorty header on those?

I recommend Twisted Wedge heads and BBK long tubes and offroad x pipe and dynomax exhaust
