69 302 budget build

I got a 69 302 with a 2bbl intake. I also have a set of 351 heads. Will these heads work on the 302? I plan on buying a rebuild kit from summit unless there is someplace cheaper? The block will need to be bored out, so what pistons should i get? What cam and intake will compliment the heads decently? I want to use this engine in a fox body and want to retain decent stream ability, but want it to sound like it still has something extra. I don't want to spend a whole lot on this engine, I have about a 1000 to use. What other parts are going to make it a fun vehicle to drive? Any advice would be appreciated for I am new to the gas world and this website. Thank you in advance!!

How much HP are you looking for? And what 351 heads? 351W heads? Do you have the casting number?

I don't have the casting number with me right now, but I believe they were out of a truck with a Windsor in it. I am looking to get close to 300.

That's a very tall order for a stock headed budget rebuild. Get the casting number off those heads and we'll go from there. 351Ws seemed to always get the worst heads. Let me rephrase that: For much of its life the 351W got the same crummy heads 302s (5.0s) got. Yes, I mean the exact same heads.

Well with $1000 that is a tall order as that money will get eaten up with the rebuild.

With factory heads 300 will be difficult to achieve. Also there were a few variations of 351 heads as most were glorified 302 heads which are wheezeeeeyyyyyy.

What intake and carb will you be using?

What do you mean wheazy? I plan on using a 700 Holley that I have on a shelf. Is that too big? Once again, completely new to gas engines. Why don't you suggest parts that i should get to get me close to 300hp

I am in a similar situation and have found the stock Ford small block Windsor heads are so restrictive they simply do not support decent power building. There are some late heads called GT40 that are OK on a budget but to really make the power takes aftermarket heads. If your Holley is a Vacuum secondary it should be fine .

Search here for GT40 heads and tons of info will come up. Nice budget head if you like to junkyard dive some. Worth it

Ok. I think what I am going to do is get it going first. Probably build the bottom end a little, forged pistons cam, etc. What cam would be nice?

Cam depends on your heads, intake, what you expect from the car, driveability, transmission ect....ect....ect....

I have an AOD to put in. But if the car I purchase has a manual, it will stay a manual. Also I plan to save up for a set of trick flow heads. I have heard they make decent power and aren't too hard on the wallet. I want to have pretty decent streetability, but wouldn't mind a small lumpy idle.
