I need some advise on a good build for my 302. I told by an old mechanic that my heads were 270 horse heads. what would you put in this engine to compliment these heads. What size cam I do know I cnnot go bigger than a 488/488 lift without major machine work.
I have a 600 Holley for the 302.
hope you can help me here.
I would suggest selling your 302 and going to a 429/460 the torinos exspecially the 72 later cars are pretty hefty cars and need the torque of a big block to pull them around.
I had a 70 torino with a built 351w and done the 429 swap (stock 72 stuff with a cam and pre 70 timing set ) and i can tell you there is no comparison in either torque or milage.
If you are set witht he 302 stay with a low rpm cam to help low end torque and stay conservitive/torque biased with your setup.
We had two '72's, a green Sport fastback and a yellow four-door. Those were the days...
installan H.O roller engine and EFI.Not really that hard to do.
Older motors are not roller and the 302 has the original firing order so if you’re going to stay small block my recommendation is retrofit the lifters to fit the roller cam, now you off to a good start any late model cam will fit.
Retrofit = expensive......
Give this guy a shout.

270Hp heads??? On A '72??? Get another mechanic...
are you sure they are 302 heads?
since you have the heads,, get the casting number,, then scroll down and find em in the list.............. the red hilite is what i have on my 302 block but retro fit with 7/16 studs and roller rockers, 1.94I / 1.6E valves as well as .040 shaved and .040 over pistons.

*******GT or GTP stamped next to number 1 spark plug
*******1996 is the magical confussing year for the gt as it may also be on SUV's.
*******Dont forget these appear on 351 truck engines as well.
*******obtain headers off doner as well
*******obtain larger throttle body/upper /lower intake since they flow better
*******concerns...existing piston clearance
Turbocoupe50 has some advice for you>>>>
"""It's ONLY the '86-UP SO engines and all '86 HO(also '87 in LSC) engines that have flat top pistons that have valve clearance issues... All the earlier engines HAVE valve reliefs, though they probably arn't large enough for some aftermarket heads and cams...""""
*******drill head bolt holes larger if used on a 351w.
351*/ 71-71 / The 351 Boss was a one year deal... '71 ONLY... In '72 & '73 a lower compression Cobra Jet 351 version was available that was similar to the '71 Boss motor... A few Torinos got the CJ in '72-'73 in addition to the Stangs... I'm assuming the Mercury models received them as well...turbocoupe50.

There no way i would keep the 302 in that size of a car does not have to have a Big Block Ford but no smaller than a 351ci Engine. Post a few pics of the car.

Does not sound great to me!
I would at least find a 351 to play with.
