Would you guys want to change something in this combo?

The engine is as follows:



According to engine builder (MDG Performance) it dynoed at 720-740HP@5600-5700rpm on 91 octane.

Planning on switching to and adding:
Exhaust: Stainless Marine Gen III with 5" dry tails
Intercooler: Superchiller
Tomas get rid of the receiver groove gasket, Fel-pro # 1012 and mill your heads to clean surface. Check the CC on the head and order a Cometic head gasket with the proper clearance to your CC`s. Cometic can make the thickness up-to .76 inch thick. A solid roller cam will light up your engine.....

Thanks Albert, do you recommend any perticular cam in this case?
If possible, I'm looking for 750-800HP and a descent fuel consumption.

WIll boost referencing the carbs do anything for the HP and/or fuel consumption? Will it make any difference or is it neglectable?!

Tomas, you want a cam that has around 672 lift with a 240/250 duration and a 112 lobe seperation. That will give you plenty of midrange accelleration and torqe. Remember, you want a solid roller cam to achieve all your goals.

Only in a Dyno any change to carbs and jetting can be done correct, just by checking your spark plug out in the water wont cut it.

Yes I will of course dyno the engine when it's done, The dyno guy just rebuild the dyno for $7000 with two new turbines etc.

Im not a great boost refernce fan I dont see a real need.And boost reference will not make any more power just change the fuel curve in the mid range.
