Hi,
I'm not a big poster on the board but do follow it quite a bit.

I'm having Race-Prep in CA building a forged 383 for me. It will probably ship (I'm in NY) out within 10 days. After that there is still about a months worth of work (suspension, DFI 7, etc...) that has to be done before she's running.

My head flow numbers were just about the same as Chuck97ss (a lot of controversy on the topic)

So we will see how the project turns out, I will post updates as they’re available.

Jim

PS. What’s the best engine simulation software out there?

 

Sounds interesting, let us know when you get it running and what numbers you end up with.

 

by the way, here are the flow numbers for the heads.

Intake:
Lift cfm
0.050 40
0.100 75
0.150 105
0.200 135
0.250 168
0.300 194
0.350 222
0.400 241
0.450 258
0.500 278
0.550 293
0.600 311
0.650 331


Exhaust:
Lift cfm
0.050 25
0.100 52
0.150 76
0.200 103
0.250 122
0.300 145
0.350 167
0.400 178
0.450 191
0.500 198
0.550 206
0.600 217
0.650 226

 

What cam are you going to run. I wonder if there is any hyd roller that can take advantage of those high lift flow numbers.

 

230/245 @ 050” lift is .622/.640 w/1.6 and a 114 lsa

Hyd roller.

 

Looks good on paper, let us know how it turns out. Good luck to you.

 

Are those flow numbers with stock LT1/4 castings or aftermarket?
