So, my spelling is awful, and this thread probably exists in the past, but Venture Brothers is on.

My question is this: I have the H.O. 302. I am considering buying GT40 Turbo Swirl heads from American Muscle (Or Jegs, I think they are cheaper there). What would be the best intake to match those heads? Would the B303 Ford Racing camshaft I currently have in the engine work well with the heads? Would I have to upgrade my injectors, which are currently 24lb injectors? Would I have to upgrade the throttle body as well, which is a 65mm TB?

Several notes: I can't call the companies, such as Ford Racing and Jegs and American Muscle and Summit, because I'm on HST (East Coast is six hours ahead) and work early to late and most weekends. I don't understand injectors other than the principles, so I have no idea what 24lb injectors really are (first time playing around with a non carb engine).

A B303 cam, 24lb injectors, and a 65mm throttle body will be just fine for GT40 heads.

What intake are you using? What size MAF (mass air flow sensor) are you using?

ASK BERNIE!!!!!!!!!!! B CAMS FOR EVERYONE

IMO, spend the little extra and go Edelbrock.

The intake is the stock 1991 H.O. intake, and the mass air flow sensor I would imagine is stock, as I haven't messed with it.

I would go trick flow or edelbrock matching heads and intake for that. 24# injectors and 65mm TB are fine for that. You should get a 70/73/75mm MAF to line up with the rest of your combo, along with a 110/155 lph fuel pump. There are better cams than the B303, which is pretty dated, but you have it in hand, so I don't know that the difference is worth the cost. It will be a nice running set up if you do all this.

I'll look into the parts. Might as well check the fuel pump and MAF, because I don't know how big they are.
I was looking at the B303 and comparing it to the E303 and F303 (I think that was them), and I got the general impression the B303 was best if you wanted a street car that didn't need to idle at 1500+

Well I would consider upgrading your intake to a GT40 intake (or better) to match your combo, as well as a 70mm+ MAF sensor to match the 24lb injectors.

The E cam is street legal, and will idle the best of the three. The F is a little more radical, with the B cam in the middle ground. All three are dated designs, and newer cams will perform better, but again, since you have the B in hand, I'd probably throw it in there unless you want significantly milder or wilder. The newer cams ramp up quicker and will have split duration favoring the exhaust a little. This can give you a little more power (and/or smoothness) over the older designs, nothing radical, but a little bit.

if you are gonna run the stock intake there is NO, I repeat, NO reason to put heads on it. if you are gonna run most of the intakes on the market it really wont matter what heads you run because the intake will be the restriction. unless you run a TFS R or holley systemax 2. if I were going to run a package on a stock 302, I would do a TFS R, and a set of 170cc TFS TWs. I would run those heads because when you build a 408 later, you sent the TW heads to TEA or whoever and have them run a 205 cnc program through them. with the above heads and cam combo, I would do an Anderson n41 if u wanted to run off the shelf. if it were mine id run bullet lobes:

intake: HR271/332 on a 112* ICL and exhaust: HR275/330 on a 115 centerline.

I had an E cam and it idle'd good at 800rpm.. No surge or anything else like that. Just sat at 800 all day.. Unless it was super cold outside then it wanted to die until it got a little warm. Had a good loping idle.

They make new pistons every day, so why worry?
