BOSS 302 Rod Length Question

[FireSale]

I'm building up a crate BOSS 302 block (the accepted S/SS one) for GT in my 68 Mustang coupe. I want to claim the BOSS 302 from either 69 or 70, but NHRA has issues with rod length. On the 69 blueprint, the BOSS is listed with a 5.155 rod length while the standard 302 has a 5.090. Turn to the 70 blueprint and only 5.090 is listed for 302 with no seperate BOSS up on the top. The 290HP blueprint specs are the same on both pages, so the BOSS engine is mentioned for both years but not named in 70.

"Independent Research" tells me that both the 69 and 70 BOSS 302s had 5.155 rods, so I assume NHRA made an office mistake and omitted the rod length info for the 70 BOSS from the blueprint.

Being the smart *** I am I had decided to build using the easier to find 5.090 rods and present the blueprint to NHRA if they ever called me on it, but after the $1000 fine deal in Ennis, I'm rethinking my strategy...

Here are my options as I see it:

A) Build as I had intended with a QF 780 carb and bracket race it this season. Rebuild with 5.155 rods over the winter and go GT/ next year. I don't have a trailer, so I will only sit out two or three Lucas Oil races.

B) Switch to flat top pistons and a Holley dash number carb, claim the 68 260HP Cougar engine and run GT/ this year. Would have to wait for the pistons.

C) Build as intended and claim the 1970 290HP 302 (with no reference to BOSS) like the blueprint says and take my chances with the NHRA tech guys.

Any thoughts on this? And yes, this is a rookie mistake...
