Hey guys/gals. Have not put a build up in a little while, just swamped here with Mopars.
So here is a little ditty we just got done with. A real budget build. We did try a few "NEW" tricks with this engine and I have to say I was very happy with the results. So without further ado, here is the basic run down.
360 block 4.030 bore
SCAT 4.00 stroker kit Icon 21cc dish pistons
Stock 360 iron head 2.02/1.60 Stage 2 porting
Old school Weiand DP intake
Stock stamped rockers, ratios were all over the place
Voodoo 704 HFT cam 234/242 at 50
Kevko stock appearing oil pan
9 to 1 compression
Rhoads lifters for a super flat power curve
Proform mech carb
FBO ignition(out performed the MSD by 6HP)
Idled well at 850rpm pulling 15" vacuum
This was no Barn Burner, rather a mild torque generating everyday cruiser. It was so smooth, so mild, like Butta! LOL
All pulls were made from 3000-6000rpm. So we will look at the peaks first
449HP at 5400rpm
477TQ at 3900rpm
Now for the Meat.
Started the pulls at 3000rpm, it was already making 455tq and held 450+tq to 5200rpm.
It hit 400hp around 4450 and held that for the rest of the pull. At 6000rpm it was still making 430hp.
Again, not the most powerful thing, but that's not the point of this build.
Our chamber mods did well(sorry, no pics). We tried timing at 32-34-36-38. It liked 34 the best. We normally see that with good closed chamber heads, not these Giant 79cc open chamber heads. And at 9 to 1 with a big open chamber we were not expecting to see our BSFC in the mid to low 400's. That showed us our mods were working well. Exhaust temps proved it too, hanging around 950-1100*. That's pretty good for a low compression, no quench engine. We normally see these kinds of numbers with high compression engines running race fuel.
