302 Boss

Anyone out there built a 302 Boss with modified 351 Clevo pistons.

I am using
302W 3.0" crank
302W 5.09" rods
and 2V 302C heads
Don't want to buy TRW or FM Boss pistons.

Regards
Stephen

Boss 302

Unfortunately you can't use 351C pistons, you need Boss 302 style pistons.

The catch is the Boss pistons are made for a Boss 302 rod which is a different length (longer) than a standard 302W rod. (5.155 vs 5.090)

If you need any Boss 302 rods, check out the for sale section!

Ps:
The Boss rod is 10 times better than a 302W rod. It also has 3/8 bolts instead of the weak 5/16 standard bolts.

Re: 302 Boss

You mill 40 thou off the top of a TRW 2379F piston to run it on the standard 302W rod. I have a set of modified pistons in my garage. Upgrade to ARP pro series rod bolts (220,000psi) and you get a good combination of strength, pump gas friendly (but not weak at the knees) compression, and a moderately cheap build price.

Good luck

cool 302 Boss

XAFALCON,

Excellent. What I wanted to hear !!!
You sound like you are talking with 302 Boss experience.
I was thinking of what you were doing but would like to know what the max valve lift your were running, head cc and comp ratio and end deck height.
TRW 2379 I think are 1.65" comp height and std windsor is 1.605".
Take 40" off and you have 1.61" comp height I think this would leave your piston just below the block by 5". Is that enough.

8.205 - 1.500 - 5.090 - 1.605 = 0.010" (10") std
8.205 - 1.500 - 5.090 - 1.610 = 0.005" (5") 2379 40" off

Anyway are you selling yours ???

P.M me as this is probably too technical for the other Forum Boys.

Re: 302 Boss

Im very intrested in the boss conversion also !
I went out and bought a 1970 302w to rebuild and wantto rebuild the heads for unleaded.But before i go and spend the $
Does anyone still make dual plane inlet manifolds for
this and what price am i likley to pay.
the only ones ive see for sale are used and have crazy prices attached ($800-$1000).
All the associated modifications to the engine-heads are straight forward enough and it seems the inlet manifold is the stumbling block for this mod.
Im not intrestested in manifold addaptor plates as this looks ugly and seems like a band-aid fix to me.
any info would be great.
