I am pretty certain my brother is running a set of the early/basic World heads on his 383 with a solid roller, large primary headers, and spray. I believe it was running 11s blowing through the converter N/A.

They can definitely be made to work.

i thought they were good heads back then and probably better now.11's is hauling *ss. when can we talk about building and modifying the turbo 350 transmission. lol. i still love that transmission and built them for about 15 years. it's fun to exchange ideas on them

Sorry Denny if we sound a little hash. In my daily job I decide what flies and what goes into the trash bin so we are all brutally honest.

I'm sure you can make those heads work, but there are probably easier/better options for your combination that don't have the downsides of those heads.

I think you can easily surpass your goal of 300 HP with your motor and those heads. There are potential downsides that you should be aware of and since we aren't trying to sell you anything, we can be honest about those downsides.

didn't think you were hash. little harder to get by these days than in the past. hope they work but been to the school of hard knocks before. got them set up with pushrod length,valve to head clearence last year and ready to go now.i remember when my friend dug up an old 400 sb for his 70 nova and just stuck an intake and 750 holley on it,no cam, just factory,no heads, just factory with 4:11's and some half worn slicks and just killed everybody on the street. i still remembering him laughing. seemed to be used up after about 1000 feet. but any way i'll hope for the best and try to keep you posted on the progress if there is any.

That will be very smooth on he street. wish i could find flow numbers for the heads.

what a lot people forget is that a street car (mine included) spends 80 percent of the time under 3000 rpm. i did not think that it was true until i watched my tach. for hours when i would go out for a cruise. sure i would nail it a lot because i live in the country but the 80 percent rule was true for me.yes i use the dish pistons. q-jets were very misunderstood but are great carbs for the street. i'm hoping for good torque for a short burst up to 5500 rpm. and 3:73 gears.

SO TRUE - the engine HAS to be built to suit the purpose. I think your peak will be close to 5000. With GOBS of torque. good luck.

thanks for the reply. 5000 will be good for me. this and the one in my 71 vette are the first small blocks i'v had for decades. always had the bb. last bb i had was a 14:1 roller cam, merlin vr heads 10 teens 70 chevelle so i'm looking forward to something tame.
