Thread: My Head/Cam Set up Idea (383)

Tweet

Alright, So my Plan is Im building a 383 stroker, built for a 200 shot nitrous.

bla bla forged everything balanced etc etc.

but here's My Head/Cam Idea

RHS:

220cc Intake Runner
72cc Combustion Chamber (fast burn)
Large 2.02" Intake and 1.60" Exhaust Valves (+.100 length)
Multi Angled Inlet & Radius Exhaust with Ductile Iron Seats (Out Flow Competition up to 5%)
Angle Spark Plug
Accept up to 1.550" Valve Springs and Standard Style Rocker Arms & Valve Train
Bronze Valve Guides

with a

Xtreme energy Retro fit-Hyd. Roller DUration 288/294 and @.050 is 236/242 and Valve lift is.520/.540

I want the Exhaust Valve to open a little sooner so some Compression can get Releasted sooner, so I Can run around a 10.5-1 Compression Ratio using nitrous.

and Prolly a 1.5 Roller Rocker Arm

What do you guys think?

Also Have another Random Question

You Think I Should Buy Billet Steel caps for my 350, or Just Stick With the Stock ones. Im Using ARP Main Studs.

The heads I.M.O. are to large.
I would look at heads that are 190 to 200 cc port volume.
Also if you want to run the 200 shot I would run a min. of 10 degree's more on the exhaust side 12 to 14 would be even better.
I would also run 112 or 114 l/s.
If money where not an object I would also look at cylinder heads with a high exhaust to intake ratio.
A good example of this would be the AFR 195 cc head.
At 600 hp I would look at splayed caps.
Over 650 and I would look at an after-market block.

Yeah, i was Afraid of having to go Aftermarket block Route.

Dart Little M Blocks are pretty Spendy
