Hello All!

I am looking to build a boss 302 Engine for a 69 Clone. How do I go about getting the 351 C Heads to fit the 302 Block. Also, What crank, rods, pistons, do you recommend? This will be a street and strip car built in the Old Drag Style with the Straight front axle, and a 4 and a 1/2 inch lift.

I want this engine to have the same performance as the original Boss 302.

Also, is there a way to put threaded frost plugs in the 302 Block?

What year of block do you recommend for a build like this?

Thanks to you all for your time and info.

E-mail me at [email protected] with your help.
Just another mustang lovin' nut.

Welcome to M&M

I'll let the Clevor guys give you specifics, but I believe the coolant passages require modifications to adapt Cleveland heads to a Windsor block, and a specific head gasket I imagine.
Boss 302's had four bolt main caps and 289 length connecting rods if you're that interested in 'originality'. A 289 HiPo block or Mexican 302 block would be the next best choice. Or, if you really wanted to go crazy, a Dart 8.2" deck block already has the 4 bolt mains.

Crank, rod, and piston choice depends on how high you plan on spinning it. Those heads will need rpms to get breathin' with only 302 cubic inches on tap. Forged bottom end internals and a very light, rock-solid valvetrain will be necessary.

With the appropriate tap ($$$ ) I can't see why you coulnd't use screw-in freeze plugs

Hello there

Sweet Ride!

I'd like to be able to spin this engine to 9500 RPM, without any problems. I plan on using a set of 1974 351 Cleveland Heads. I haven't located an intake yet.

Also I would like to know if I could beef up a regular 69 302 Block or a 66 hi-po 289 Block to run this kind of power.

How do I find these Clevor Guys?

Thanks for your reply. Look forward to talking in the future.

Ryan

Thanks for the compliment

Try posting something over in our Racing Forum regarding Cleveland head retrofits. Not all of us hardcore horsepower junkies browse the entire site, you may get more feedback over there.

They're quite a ways from your neck of the woods, but here's another contact:

Ford Motorsport R-302 racing block is another option. For ultra high rpm use, I personally would not even concider a 'run-of-the-mill' production block; certainly not a standard 289-302 casting, or even a HiPo or Mexican for that kind of abuse. JMHO

Living on the ragged edge aren't you? Is this going to be a street engine or full race? To turn that kind of RPM's, you are going to have to invest in some seriously expensive race only parts.
