[email protected]
Int. 258
Exh.262
Lift is .629 on both
Lobe sep. is 114
which heads would you guys pick? thanks.

I have heard good things about RHS. I just ordered two sets for my motors, so we will see, fingers crossed. Everything I read as far as build and dyno pulls shows dang good numbers, even compared to heads that cost waaay more.

What are your goals? Off the shelf or custom ported?

Looks like a Whipple cam.

my goals are whatever is cheapest with the most amount of power. I think the cam come from bob

Going with a blower ? What kind of power are you looking to make ? There is nothing cheap when you start building big inch motors .That said the cheapest part is the short block . just saying

fast, cheap, durable. choose any two. those inches though you need fairly big chambers. even N/A.

Brodix BB2 xtra CNC BP BB-2 X TRA
(CNC Ported) 2.300 Intake 183 235 294 340 376 395
1.880 Exhaust 134 177 216 247 268 280

Good blower cam but to much compression with flat top's for a blower .

its going N/A. Im not scared to spend the money but Im just like everyone else id like to find a deal
id like to see 750hp out of it
