question on horsepower amount

[EHardy1971]

What gear ratio/rear end setup are you planning on using?,that,and tranny is another dictating factor as well!

One step further, What tire size and chassis weight.

if you want accurate help give enough info for an educated guess.we cant give you much help with out all variables

Tire size would apply to how much power and torque are getting to the ground.Chassis weight would'nt affect horsepower,only times.

So far 1sicklx and Matt are dead on!

HP prediction: Too many variables to make a prediction, But the way youre headed it would be fun in a tow truck or daily driven 4X4.

Camshaft: There is way more to a cam than lift and duration, Lift and duration are a by-product of timing events and lobes chosen. A good cylinder head needs good clean charge of fresh air, This means little to no overlap and the use of faster ramps. Advertised duration and duration @ .050 gives you an idea of how fast or slow a ramp is as does LSA. Cubic inches, Total combo and desired operating parameters dictate the cam needed. Optimal for a "Streetable" application is a wide Tq curve, This means you have to be careful picking your parts or the camshaft will have to crutch a poorly chosen combo.

Streetability: This is like asking opinions because everyones perception of "streetable" is different, Mine is if it will idle its streetable.

Intake: Dale has my old Probe/CHP EFI Spyder and I think he is looking to sell it, It is new and is not a Chinese knock-off(original Eddy Vic Jr.).

i know all of this i aint retarted. my intake has bigger ports on it than the heads do. i am gettin the edelbrock sr. heads with the 210cc intake runners and 205 160 valves. and a 60cc combustion chamber. i am gonna call comp cams and get them to pick me a cam for my set up i am figureing a mild cam for it will be around high 500s to low 600s for lift with like 276 and 280 duration with like a 112 lsa or something. i am also going to be running 36s or 42s. not sure but gonna find out. i am looking for around 450. i know it could be way more or way less. i am just trying to put a parts list together that "should" work to make what i want.

i have a stage 3+ spec clutch with a tremec 3550 aluminum driveshaft and 3.73s and auburn posi as of right now. i am getting a rear end girdle while in the process of all of this.

An 11.5:1 408 with a set of AFR 205 heads,a carb style Vic Jr intake converted to EFI,elbow,75mm throttle body,1&3/4 inch longtubes,80mm mass air,42 lb injectors


Oh and call and have a custom ground cam made....dont build a custom motor and then get and off the shelf cam.

I never said you were, Just trying to help.

One major problem though with the intake, Its not really the size of the port but the length that hurts you. The intake will be a major bottleneck if your looking to make power above 4500rpm.

The heads are not Victors but more than likely Victor Jrs, Eddelbrock Victor cylinder heads are a 15* head. They require special pistons and Victor specific shaft rockers not to mention they come with larger intake valves and ports than what you posted. Anything short of a converted Vic jr or Super Vic intake would be a waste of time on a Victor headed engine.

Sorry I got in car mode and out of engine mode. LOL

850 Holley DP with a super vic or air gap intake if your gonna stay mild. The $$ you save will be worth it. On the cam choice id call Bennett Racing or Ed curtis @FTI Plan on saving some money for an astro a-5 kit or a tko600 after you break that 3550 in a million pieces.
