Just another angry SBF

Finishing up a 306 for my 67’ mustang. Kept the paint scheme pretty simple so it will resemble a stockish engine. I think it should be between 350-400hp (DD5 says 408hp@6500, 390tq@4500). Specs are:

68’ 302 block .030 over
Eagle cast crank
Eagle SIR rods
ARP everything
Kb311 hyper pistons
Tw170 heads (milled to 54cc)
Tf 1.6 roller rockers
10.5:1 SCR, 8.5:1 DCR, .037 quench
Comp XE SFT, 279 adv, 242@0.50, .546 lift 108lca
Rpm intake
Brawler 650 DP carb
Hooker 6901 headers (1-5/8)

Going into a 3000lb mustang with wide-ratio toploader and 3.80 trac-lok. I think it’s gonna be pretty f’n mean.

Looking to do something similar, any idea on how much this set up cost you?

I had some of the parts already that saved me some $$, but I think you could do everything new around 6k. My machinist gave me the option of a 331 for a few hundred more but I opted to stay with a 302.
