Is it possible to convert a '69 302 2v engine to a 302 Boss engine? If so, what kind of job would I be looking at?

I asked this question quite a while ago, and I got replies that said yes, you can....but I don't know what it requires. Good luck.

if you want to build a 302 to LOOK like a Boss 302 it is possible, but keep in mind it is not the LOOK of the boss 302 engine that makes it so boss. Starting with the block, the boss block as opposed to the standard 302 block is a 4-bolt main, high nickel content, near bullet proof casting that was needed for TransAm racing. The crank is forged steel as opposed to the standard cast crank in a regular 302. The rods, specially configured forged pistons (due to the mating of the Cleveland heads), solid lifter cam and so on set the Boss apart from the passenger car 302s. As I said before, you can build a 302 to LOOK like the Boss 302 powerplant, but it can prove to be more expensive than its worth.

In my opinion, if you are out to build a powerplant with performance, you can do much better using today's technology by building a stroker 302 (ala 347) or even a stroker 351W (ala up to 427 and beyond) and topping with any of the excellent designed, high flow aluminum heads available. If you really want the look of the Boss engine, email me and I will guide you along in the components and necessary machine work that needs to be done.

Randy outlined the details...

Figure, with a new SVO 4 bolt block, aftermarket steel crank and rods and a set of vintage heads that you'll have between 4.5 and 7K tied up in the project, depending on the deals you get...

What you'll end up with is a somewhat tweeky, designed for racing at high rpms engine...

Trust me....build a 351W with aluminum heads as Randy suggested and you'll likely go just as quick or quicker with a lot fewer headaches...

That's sounds like more work and money than I'm willing to do/spend. Guess I'll just try and modify the existing engine with some aftermarket goodies. Any suggestions?
