I went up the other night for the pull and wanted to see what my forum fam think it made.
SBC 383
hydraulic roller.575/575 lift,236-242 duration.110 lsa
11.03:1 compression
AFR Eliminator 195cc heads.2.08-1.60
Edelbrock rpm air gap
670cfm vac secondary

 

[Texas82GP]

It's a W.A.G., but I'll say 430 HP.

 

[DSPbuilt]

Engine dyno I assume?
466 FWHP

yes engine dyno

 

[Streetbu]

455hp at the crank

 

[DRIVEN]

I'll bite -- 400 even. It wanted more carb.

problem is every Dyno is different however I have a sbc 406 with the same setup, more lift .590, performer rpm intake and 750 cfm mechanical secondary, 481hp 517 lb ft all under 6000rpm, so I would say 30 hp less
