Going to dyno my 496 tommrow. I am so exited!!! Just wondering what everyone thinks it will make for tq/HP Specs 496 Using Muscle Motors kit. Should be little north of 10-1 Compression Edelbrock head CNC ported by Modern Cylinder heads. Flow 328int/268ex. Solid Roller cam by Straighline w 1.5 rockers. Intake .645 Duration 300 Centerline@108Ex. .626 Duration 314 Centerline @116 Intake is a ported Holley SD to clear my hood on my RR. Also going to try a M1 on the dyno 950 Demon for a carb.

I've never been to the dyno, but I'm guessing I'm around 570ish and he has WAY more engine than I have...and 50 more cubic inches.

Roller lift/duration is well matched to the Modern CNC eddies. If the SD is ported like I do them that motor should EASILY make at least 635-640 Hp and either way it's gonna be a near perfect street/strip brawler, perfect for 3.54 gears. Out of the box a SD will flow around 270, ported they can go over 310. Very similar to my old 508 which was a 610hp recipie with a 252/258 straight line hydraulic roller and ported iron Stage V heads. Either way, I like the combo a lot but I'd prefer (having run both) the tighter 108 lobe spread for a little more "hit" in the 2500-4500 'fun zone'. Nice combo....I predict.... happiness

how can you say a guy that has 56 more cubic inches is only going to make 30 more hp?
