First of all 75mm TB is way to big. 65 or 70 is good.

Without spray---220 rwhp TOPS
With Spray---260 rwhp TOPS

Assuming your motor is healthy and in good tune.

Your heads are choking your motor from making good power...also you didnt mention a good fuel pump.

Pretty much have to have one with the spray.

Just some friendly advice, I wouldn't run the 75mm TB. Might be a good idea to even go down to a 65mm. Basic rule of thumb is not to use a TB bigger than your MAF meter.

Not sure about how much power you will put out, I don't want to guess and get a bunch of crap for it.

Maybe 230 rwhp and 280 ft/lbs no spray
275 rwhp and 325 ft/lbs with.

Again assuming that is a 5 speed also.
