I totally want to do a javelin, It's just so much effort to get good race parts. For example it took me a year to find a good 401 core for a decent price, and even that wasn't exactly cheap.
The rules for javelins call out a 310 CI max engine

so I would then need to de-stoke and possibly sleeve a 401 block. (Waaaay better than the 290/304/343/360 blocks), then figure out the appropriate crank and either modify a forged 401 unit or sell a kidney and get a moldex custom crank. I could build an old cast crank 290 but then I would be either last or I would be the guy that oiled down the track on every outing.
If I do a ford build I simply dial up FORD and order a NEW boss 302 block and get a good forged 302 crank from any number of places for a fraction of the cost.
And what if I crumple a rear fender
I was just hangin' around the three original race javelins this weekend to and man were they sexy!
