I have an 84 F-150 stepside with a 302 2 barrel carb that is all stock besides a set of headers from a mustang. It also has an AOD tranny swapped in. My question is, is there a certain year that a Ford factory intake and 4 barrel carb from a mustang or other Ford vehiclee fit this motor and work? I understand the linkage for the kickdown might need to be fabricated. Just looking for more power with out spending a fortune on new parts. My budget sucks, besides I love old grassroots hotrodding. any info would be great!

 

On that motor the route to more power is in the cam and heads, changing the intake and carb won't really do much. Changing the cam is certainly not a small job..you basically have to strip the motor bare, but it's easilly the best bang for your buck.

 

What cam would you recommend? I thought about the smallest cam of the "***** thumpers" series by Comp. Nice aggresive idle and their flat tappet hyd. lifters too. Not as expensive as the retro roller series.

 

Compcams 35-234-3.

 

All small block 4V intakes will fit on a 302/5.0L. The 1983-85 aluminum Mustang intake (which came with a Holley carb) is an obvious candidate.

Or you can use a cast iron 289/302 4V intake, they were made from 1963-68 and installed on various cars. Also a marine version was offered for many years after that.

Stock intakes are pretty cheap at swap meets these days.

 

Thanks for the info.

 

Not trying to hijack the thread, but I have a 302 also.

Paul, how would the cam you have suggested perform with the 77 stock 2 barrel intake, but using E7 or GT40 heads? And would changing the valve springs be absolutely necessary? I have a new 500 CFM 4412 holley carb, and full length headers.

 

The stock 4bbl and 2bbl intakes are pretty similar and neither could be considered a high performance piece so that's partly why I don't think a 4bbl swap is really necessary to get more power. Once the cam is changed the carb would have to be rejetted for sure, new valve springs would certainly be a good idea on an engine with some milage but they're not absolutely necessary if the current ones have low miles. The cam mentioned is bigger than a stock cam but it's still well within the capacity of the stock springs.

 

To clarify my earlier post, what I mean by "small block" is 221-302 engines, not 351s or Boss 302s, although they are also sometimes considered "small blocks".
