I have a 427 bbc with balanced forged crank scat rods & forged wiseco 9.5 pistons.Will 110 cc e-street heads work with a SLRcam 532-522 lift & 282-292 duration.The valves are .219-.188.Will I have enough compression?.........Gus

what are the specs on the pistons. Dome volume, deck clearacne @TDC.
What is that camshaft? Clairify.

E street head chamber wall to piston dome may need a bit of hand clearancing to fit.
This must be checked.

"wiseco 9.5 pistons" not enough information. get the piston dome volume or piston part number.
The assembled deck clearance @TDC matters.

valve to piston clearance (relief depth and valve radial clearance) must be checked when building non stock BBC's.
Do not assume anything.

You can use this to find the dcr of you engine with that cam then find out from others what a good dcr is for your engine head combo.

United Engine & Machine Co. Incorporated

Not sure what a good dcr for your app would be. Most ppl say 8.5:1. Small block chevy can get pretty high compression ration with big cam and alum. Heads.

Hope this helps.

E-street heads

Sounds good, The cam is a Steve Long Racing Cam . Don't know of a web site, but it's out of california. Any idea what kind of power it'll make ? I'm using a Weiand Hi-ram w/ two 600 eddies .Thanks again.............Gus

No idea, but it will run well. That's what they make dynos and drag strips for. But...Can make more power with the Hi Ram manifold, using a bigger camshaft.

A solid lifter cam or solid street roller cam is preferred for this, on a BBC. That cam is mild if you are after horsepower with the Weiand Hi-Ram.

10:1 is plenty compression for a BBC on street premium pump gas.
The eddy 750's are a better choice for power on that manifold.

The two cams you got are not very different.
Need to say more about what car its going in and what you want to achieve.
Details.

I'll be running it in a '23 T bucket-2-spd Powerglide ,narrowed 9", 355s,Eaton locker, wide mickeys on the back. Iwas running it in a V-drive boat,hence marine cam. The bucket has a 454,but I thnk the 427 will be better,it only has about 10 hrs since the overhaul.I had just put the aluminum heads on the 454 & cam etc ,but the rotating assembly is stock.

So you are not trying to make serious power. More of a street cruiser.

It will work well for that. The 600 edelbrocks are fine for this with some jet/rod tuning.
It should be a fun car. If the comp cam is not worn , its fine. (Look at the face of the lifters for convex, do not mix) I would use a 10" 3000 stall converter for the T bucket. Like B&M #70411 for Powerglide trans. This will keep the light weight car from pushing/creeping at idle when idling in gear stationary.

If you find you want a T Bucket that has a lot more top end power and rpm ( beyond about 5500 rpm you
can step up the cam. As the tunnel ram really likes to rev and make top power.
A lunati Voodoo solid street roller would turn it into a dragon slayer.
Lunati cam # 60232 60233 60234 Must use correct valvetrain.
Now you will be starting to use that Tunnel Ram manifold. It will pull and pull and pull like you never seen.

You'd best hang on tight with any of these. You would have liked one of these in your boat with marine headers and the T Ram too. Powerfull cams designed for the street.

I like to and recommend "cold lash" instead of hot lashing. When you do that set the cold lash about .004-.006" tighter than the hot lash spec on the cam card. The lash will be right on , at warmed up engine running temperature. very simple, easy painless lashing. These powerfull street roller cams are easy to keep up on. Most people are needlessly intimidated by a mechanical lifter camshaft. Big Block Chevys really really like a mechanical cam for powerformance. When you get beyond 5500rpm.

yeah it's a lot of fun,I forgot to mention it has a billet 3000 stall & transbrake,just had the tranny done supposed to be good for 750 hp..Car weighs 2200 lbs.Maybe I'll leave the Comp. in I'll have both motors on the engine stands,so either way it's not a lot of work.Thanks again for all the info-appreciate it..............Gus

You will probabily find that a street performance oriented power glide with automatic shifting in drive
and shift accumulators (valvebody) to soften part throttle shifts when driving makes the T bucket a lot nicer to drive around. A full race manual valve body race transmission gets old on the street.

I'm a retired truck driver so I don't mind the manual shift.
