383 stroker advice
Bought parts a while back to rebuild top end of my '77 L48 for more power,-
edeldrock rpm 64cc heads
edelbrock eps manifold
670 street avenger
mild voodoo cam
hardend push rods
roller tip rockers.
But now the more i read about 383's, the more i want one
I figured by the time i buy a stroker kit, have someone clearance/install it into my L48 block, i could get a complete rebuilt stroker short block for near enough the same money and leave the original engine complete and put it to one side.
Looking to build a fast street car with bags of torque.My vette is a '77 with 4-speed borgW and 3:55 rear gears.
Looking @ motor around 10-1/10.5- CR when built.
Questions(bear with me,first build)-
Is this inlet going to strangle it,or will it be ok for now? OR go with edel rpm inlet? hood clearance?
(want a rpm air gap,but hi rise hood/paint job is a future project)
Should i go with a 770 street avenger,or stick with the 670, as holley say 300hp+ =670, 400hp+ = 770. Im guessing the motor will make around 400hp
Would like to go with another voodoo cam,what size to look for. Any stroker clearance issues?
Any thing else to consider/look for?
Any advice much appreciated.

A 77 can clear a edelbrock RPM manifold with a drop base air cleaner.
The 770 would be a better carb for a 383. As for a cam for a 383
with 4 speed and 3.55s I would use a cam with intake dur. at .050
230 or around 280 adv duration on the intake.

My 388 stroker is my original engine, rebuilt. It cost me no more than a standard rebuild and the engine needed it at that time. However, this was done in 1994 before the booming popularity and lower cost of today's crate engines. If I do it again, I would definitely go the crate stroker route.....you can order your engine with mega cubes for the same price as a good rebuild.

Looked at rebuilding/stroking original block etc,
but importing a complete short block here into the UK will run me near enough the same cost as rebuilding/stroking the L48 block, only difference being is i get to keep my original engine aswell, for future no. matching(
) or mild rebuild for another car-whatever,plus save time and potential problems etc.
Want to build the rest of the engine myself though, so dont want to go with a full crate engine- plus the fact i already forked for these heads.
Cam specs, one ive got- voodoo dur@.050 213/219, lift in/ex .454/.468, rpm 1000-5500.
What im looking at-voodoo- 219/227, .468/.489, 1400-5800.
OR
voodoo- "268cam" 227/233, .489/.504, 1800-6200.
OR
voodoo- 233/241, .504/525, 2200-6400.
clearance issues?
would an RPM inlet fit with a lt1 style base/3" filter/k&n open lid?
Is the EPS inlet + 670 carb going to hold it back that much?
