Dreamin up a motor
 

Well I'm startin to think about what I'm gonna build this summer to put into a monte ss since that idea has move from an idea to a ok I'm gonna do it kinda thing.

350 roller block

xr270hr


Summit Vortecs

Comp Cams 1.5's

Manifold

And probably a 650 holley.

What ya think? I'm aiming for under $2000 said and done.

ever given thought to a custom cam?

Nah trying to go on the cheap. Looks like this car is going to be replacing my truck too...

Most of the time a custom ground cam is only a few bucks more than off the shelf parts....

Before you order anything, give Comp a call and tell them your combo, and what cam you plan on running. See if they can suggest some tweaks to it to optimize your combo.

Yeah looks like the car is comin first and the truck is gonna go so I can commute to school.

What are your expectation of the motor? 76cc heads on a stock bottom end = flat top pistons, isn't going to have much compression. I'll guess HP to be around 260-275 at best.

9.5 compression

How do you figure that a stock bottom end will only support that? Theres plenty of builds out there reaching upwards of 350 horsepower with vortec heads simply with upgraded springs...

I don't think that's what he's saying.

I think he means that if you are doing this on a stock bottom end (which has flat top pistons) your CR will be low due to the large combustion chamber size so you won't be making that much power with the speed parts.

Although the link for your heads says 67cc, I'm not sure if he saw that.

Yeah and I'm going with stocker 64's. I was a little confused cause I wasnt sure where he was getting that number from.

Sorry, yah, ment 67cc, but that still large if you're looking for allot of performance I'd like something more in the 54-58 cc range and push compression up into the 10s. Sure a stock bottom end will support 350+ HP, but I don't thing the heads/cam you're look at are going to make anywhere that much, which is why I asked why you were shooting for?

I'd like to put anywhere from 350-400 to the crank. Shooting for 9.5:1 compression.

Not that I'm doubting your experience or anything (cause I'm the first to admit I have very little) but theres alot of people telling me I'd hit 365-375 easily with that setup.
