Thread: 383 Stroker Build

In my opinion, you're starting with the best heads money can buy and they're the correct size (cubic inches times 1/2 for intake runner size, street motor).
AFR shows five builds on their dyno website. Check 'em out.......

Look at the fifth build down.
Over 450 lbs. of torque at 2,500 rpm's.
Over 500 hp at 5,500 rpm's.
All this on pump gas and less than 10 to 1 for a comp. ratio.
This is what ever sbc guy needs.
This is as close to perfect for a street rod or muscle as you will ever get I.M.O.

Also, wouldn't you think it would be possible to get lets say 480 HP and just over 500 LB FT with a hydraulic flat tappet such as the magnum 280? I'm seeing a combo, which uses the AFR's and the magnum 280 hydraulic flat and they are claiming 471 hp and 515 torque.

It depends on how good you want it.
To be safe I would say it would add about $550 to the build price if you figure the other hyd. cam and lifters at $140 and you would need a better valve springs also.
I run a small or reduced base circle cam in any of the 383's I build.
The 280 would be the largest hyd. cam I would run in a sbc. with the removal of zinc from todays oils.
I have customers that run 7.00's in the 1/8 mile out of a sbc. with a hyd. roller cam and some even drive them to the track.
If I am building a max. effort 383 sbc. for the streets the most hp out of a hyd. cam I would even try for is around 1.1 to 1.2 hp per cubic inch.
After that I would look at hyd. roller's or mech. rollers.
