small block build up

i got a small block chevy im planning on building up for my 69 chevelle i was planning on using comp cams magnum 292h series cam and lifter kit with sum 11.1 ratio pistons also steel crank and rods camel hump heads with the 202 160 valves edelbrock victor jr intake and 750 double pumper carb long tube headers and super 44 mufflers my question is does anyone know if this combo would be a good match? looking to make 400 plus horsepower maybe sumone has sum good ideas to add in to help with my build up?  

With race gas compression and a long-duration cam your engine would probably benefit from aftermarket heads. You're bordering on power ranges where unported, factory heads are starting to lose a bit of steam.  

I agree, with your combo, I would look to the aftermarket for some better heads.  The double humps were good 30 years ago, but now there are much better heads to be had.  I would also plan on keeping my compression closer to 10.5 to 1.  

Also did you ever figure out what block you have?  

its a 68 327 block so i was checkin out sum heads online today should i get the 202 160 valves or go bigger with tha comp magnum 292h series cam?  

Unless you plan on getting a 3.48" or even 3.75" stroke crank I may reconsider using a 292° flat tappet cam. That will be very rumpity in a tiny 327. A flat tappet at this kind of duration is a bit of a waste since it will most likely make a much narrower power range than a roller of near the same lift.  

only thing i plan on using from this 327 is the block itself which is 30 over using new bottom end including crank rods pistons my father had same cam in his 327 ran great had tons of power also and i luv tha sound jus needed to kno which heads would be tha way to go with this cam?  

I'm sure it made tons of power.  

look i dont wanna hear ur smart ass remarks if u dont have anything useful to say dont say it all im askin for is sum info on heads not ur opinon on which engine i use it on.  

put some 305 heads on it and a big ass single plane inake, maybe a tunnel ram dual quad set up to go with your cam  

thank u for ur help  

don't really do any of that... Look at some vortec heads a performer RPM and an XE268 cam from comp and you will be much better served.


I was being sarcastic with the 305 heads and single plane stuff.  

decided to do a 383 storker already had the rotating kit form another project so figured i mite as well use em sent block to shop today what im tryin to do with this car is build the fastest thing on the block i live in a small town thats full of imports wanna bring sum muscle to the streets so basically jus tryin to build a hi torqe horsepower motor thats light  

I have a 383 with AFR 190 cc heads and a Comp XR282HR and at the wheels I get 370 HP @ 5600 and 400 LB @ 3900.  

sounds nice im looking for alittle more juice outta mine im gunna be runnin agaisnt turbo charged wrxs and other imports around here wanna them to be eatin rubber off the tires
