I want to get at least 550HP or better with this setup so if anyone can give me any info that can help me to make my peak of HP it would really help me out. Here is my setup below

I'm new to this, I have been always into muscle car & performance engines, so this is my first time getting a engine built for me. Im getting built a 383 Stroker with TRW forged pistons 30 over, forged scat I beam rods , 4130 Eagle crank, Airflow Research (AFR) 1095 - AFR 195cc SBC Eliminator Competition Heads & I'm going with a (Lunati Voodoo Retro Fit Hyd Roller Cam) custom grind at a 108 lobe. Part #60112
Advertised Duration (Int/Exh): 282/290
Gross Valve Lift (Int/Exh): .535/.550
Duration @ .050 (Int/Exh): 231/239

RPM is 2400-6200 but when I talked to the tech they said it can do 2500-6500 rpm.

Opinions??? Will these lifters be the best for my setup have anyone used them before??? Howards Cams Maximum Effort Retrofit Hydraulic Roller Lifters part #91160

For my Intake I want to know have anyone tried or have any opinions about AFR Plastic intake. AFR says it keeps your engine 30 degrees cooler and gain 15 extra HP??? RPM 2000-6500

first things first 550 hp aint gonna happen with that set up 450 is prolly the highest you will see.
a few things i see already that tell me its the wrong set up.

1.) the 195 cc heads are too small for a 383 you want at least a 215cc head minimum! Someone will say 195s are fine but trust me 215s are a better breathing head for a 383 even for a street motor.
2.) in order to hit that 550 mark your going to want alot of compression.

3.) you also need a big healty stick with alot of lift and duration and the voodoo isnt going to cut it.

im sorry if its not what you wanted to hear but im just being honest.

IMO if you want 550hp maybe more you should be looking at a bigblock.

you can get 550hp from a bigblock with stock heads.
ive seen 700hp from a 496 stock headed BBC

What stock heads were those and are you talking 700 measured h.p., as in dyno'd or seat of the pants?

[67-4-fun]

AFR heads flow very well especially if they are competition ported as AFR does... with the rpm range your looking at, the 195 will be just fine IMO... the 195 will flow like 210..

[vinniekq2]

I kind of agree with what he said.The math on the parts,,,you will need 270 plus cfm air flow from the heads and a camshaft to make that happen.We can crush numbers all night then debate the volumetric efficiency and argue over what carb etc,,,I see 7000 rpm solid roller with good heads and open exhaust.forced induction is a different storey.

BTW, were we talking flywheel HP or wheel?

[CNC BLOCKS NE]

You may want to jump up to the 210's and get rid of the dual pattern cam as the AFR flow pretty good on the exhaust side. And your not going to see that much power with 550 lift either or that small of duration!!

That might get you up around 540 and I hope you not using a stock block with stock caps!!!!

The last 406 I built with a Dart SHP block and AFR 210's 11:01 comprsession made 570 horse

[joelster]

I run AFR's and I would get the 210 comps if I were in your shoes. The 195's plus that cam will probably fall short of your goals. That cam is tiny for trying to feed 383 cubes. Big cubes tame camshafts.

AFR 210 comps
A roller cam around 242/246 with near .600 lift
The AFR plastic intake is a nice piece but pricey
Keep the compression 11.5 minimum

I was talking about to the wheel 550 or better...???

Yeah Im Using a 1974 block 4bolt main

That block will come apart long before you ever get close to 550 na whp. 550 at the wheels will be about 625ish at the flywheel... no freaking way are you going to hit that on pump gas with the parts you mentioned.

How did u only make 570hp, if you go on youtube and look up CNC motorsports they build a 383 stroker at 563hp with a custom hyd roller cam and a 750 aed carb with a cnc ported hamburger carb spacer, and victor jr intake At 10:1 compression ratio. So how come I cant make close to 550 just saying???

No I said 550 at the flywheel not to the wheels........

I looked on YouTube. They also had what you are looking to build.
