Blower vs. Stroker

I'm looking to get more power out of the 302 in my Gran Torino. Right now I'm looking at either getting a stroker kit or a blower. If I went stroker I'd take it to a 347, and if I went with a blower i'd go with a weiand 174 (unless someone knows of a better one). I'm currently in the "homework" stage of my build and I want to make sure that everything will be set once I start ordering parts. On a side note, underhood space may be a bit of an issue, right now the Torino has a standard hood but I plan on getting a GT hood in the future.

personally i wouldnt do either to be honest, a 302 in a gran torino is always gonna be kind of a turd to say the least, if you did go stroker it'd help but the money you spend on it you can put together a windsor for about the same price and still have lots of room to grow later. just my opinion

I agree a 302 is small for that heavey of a car... I'd spend the money on a 351 or a TADA 460 much more bange for the buck.

How 'bout a blown 408? That would be cool.

Dont waste your money on a weiand 174, im telling you go with a procharger.

Waste his money on a 174? What advantage would the procharger give him if he can only run ~8psi of boost reliably with the stock bottom end? You make a LOT more power at low RPM with the roots blower, and the 174 can push all the boost that his engine can really take anyways, right?

if you spin those weiands too fast the rotors will break, been there.

a roots blower has a very low adiabatic effieciency compared to a centrifugal or a screw type blower. you can make a centrifugal setup to produce peak boost wherever you want it......

I'll take my roots blower any day, first reason for the looks (wow factor). It may not make the peak boost of a centrifigul but I make max boost by 2k and hold even all the way to 7k. As for them not taking RPM I have had mine since 1989 on two different motors and have turned it 8k before. There is not even a blemish on the rotors. Maybe Holley has changed some stuff, mine is an original B&M but they look exactly the same. If it were me I would build a blown stroker.

If your hell bent on doing a supercharged motor, Procharger with an intercooler all the way !!! Its way more Efficient than a roots blower and will make a bunch more power. Plus it is all under the hood........

When you pop the 302, build a stroker 351 (393, 408, 427 Ect.) and bolt the procharger on again !! It would only take a little rework of a few brackets and some different pulleys to make it work.

It you want to stick N/A I'd do a 460 stroker cause their is no replacement for displacement. A N/A 347 is simple but will still be a slug compaired to even a stock displacement 460.

YOU NEED TORQUE TO MOVE THAT SLED !!!
