Starting a new thread on a motor which has been discussed a bit on other threads before.
Object is to have power similar to new Camaro and to have good street manners allowing
Coast to Coast Cruising. Street torque desired. Live at mile high level but will run to sea level.

Purchased a craigslist 383 build which I took apart and examined. Sold the Summit vortec heads, manifold and carb. Have a Holly 3310 and Performer RPM intake.
Motor is 4.03 bore, 3.75 stroke, Ross forged pistons -12cc, 6.0 eagle rods, Pistons are even with deck – zero decked.
On pervious advice from Tech on another thread I scraped together my “hot rod money” and purchased Pro Filer 195cc heads with 72cc chambers.
Using a Felpro gasket for .041 crush.
Jerry gave helpful advice on the carb setup. Tech and Roger suggested fuel injection to help with altitude changes. All liked the addition of a blower, me too. That “hot rod money fund” was not quite ready for the jump to a commercial unit. Holding that blower out for the future.
New purchase of a Holly Stealth Ram manifold with Holly Fuel rails. I like the look of the basic manifold which I think could be converted to a blower base later on. Current plan is to just run it as injection. Thinking 36lb injectors and 58mm throttle body. Holly control wiring and brain are very expensive – any suggestions there? Fast?

Basic Cam Question:
New cam that came with the motor is standard Hyd of unknown manufacture 230@.50 with .575 lift on both intake and exhaust. Could someone give me estimates or even better a dyno-sim run with that cam?
Second choice, I am considering a Howards retro roller small base circle Hydraulic cam #110245-12S (278/284, .500/.510 lift with 112 degree lobe separation. RPM range of 1500 – 5400) Is this worthwhile or can you make a better suggestion? Any chance of a dyno-sim of that setup to compare with the other?

Open to suggestions, have at it.
