Lookin at 427 bbc(not tall/truck block) brodix bb2plus heads.(cc'd at 116), srp piston #141637 prox 9.5 to 1, comp solid roller # 11-703-9 .680 lift. vic jr. intake, 800 dp holly. bassett tt headers. There aren't many .070 pistons out there , but if this combo is going to suck I'll pop for a new block. I'm considering/ have been talking a little to cstraub, wondering if a custom grind would be worth the extra $$?? Any sugestions would be greatly appreciated. OH BTW it's going in a jet boat.

Is 9.5 to 1,, too tame for any solid roller cam?? I dunno I have a set of 11.6 to one pistons, I'm just sick of needing to mix 110 with pump gas.

The cam for his compression, cid, and operating range.

That cam has some mama lama durations.

As always, take my info with a grain of salt and treat it that way.

Not at all. There's solids out there for most everyone. A 9.5:1 motor can run pretty hard.

Give a few calls to Comp, Lunati, HArold Brookshire, whomever that is on top of their game and you are comfortable with. Then sit down and decide what you'll go with.

Thanks guys, I've rattled Chris's chain so many times I'll put my cam fate in his hands.lol It would be nice $ wise to be able to reuse those 11.6 pistons.

Not a bad choice on cam guy's! :D

I'd whack a little off of those domes, blend them and cam it accordingly! ;)

Lookin at 427 bbc(not tall/truck block) brodix bb2plus heads.(cc'd at 116), srp piston #141637 prox 9.5 to 1, comp solid roller # 11-703-9 .680 lift. vic jr. intake, 800 dp holly. bassett tt headers.

Brodix heads like duration split so I would recommend going with something with some more split. The heads respond to this and customers engines have made very good power.

Dude...quit bouncing around, pick a combination, and go with it. Whatever your combination is, go with Chris or call me and I'll help you out. 805 350 1159. With the right cam your combination will work just fine. Don't waste your time going through off the shelf cams that might come close to what you need, just get the right cam and be done with it.

Ya I'm just trying to put together a short block at the moment. When I get to that point Chris will get my cam bucks. I guess I'll stick with the 11.6 to 1's and buy a new block,that's the cheaper route anyways.:)grn

These are some of the best flowing heads out of the box out there. Why would you "crutch them with split"?

Actually they're not, in fact some of the worst, depending on what you get. For example, a set of BB2X's are terrible flowing heads out of the box compared to other similar heads, but they're more targeted for guys doing their own porting, having lots of material to work with. Not really designed to be great as-cast heads. The chambers are terrible, but again, have plenty of material in the right places for a guy to go in and do just what he wants. Between them and the Canfields they're probably the best head for a CNC porting program.

So, someone tell me what "some more split" means .
And then, More split than what ?

If based off of 0 - intake and exhaust using I dentical lobes - All BBC heads will take more split than 0.

Vague, very vague. As certainly cam lobes are not one dimensional.

BTW: My wife can do splits, but I can't. Just some humour. :D

He's using the -2Plus, not the 2X's.

Here's the flow info on the BB-2Plus

BB-2 PLUS
2.250 Intake 150 215 265 311 334 344
1.880 Exhaust 122 148 187 216 229 238

===================================

It doesn't appear to be that bad of a head out of the box. It should totally work on a 427 running some compression and rpm.
