been searching around trying to find a set of suitable heads and im thinking maybe instead of using a 76cc i could running a smaller more abundantly available size cc head and run a thicker cooper head gasket (.093 compressed thickness) i think a 64cc head is widely available and cheaper and the titan copper head gaskets seem to be a good choice as far as increase my cr in order to run more boost and to seem the boost better what-da-ya think?

if u want real turbo advice check out the turbo forums, and btw that ebay gt45 is not sized the same as a true gt45 turbo its actually nothing more then a 70mm turbo with a larger turbine wheel, will still make plenty of power though 650-750 should be reachable with it

i can first hand show u a engine with crappy small valve truck heads and a tpi intake that has gone 9.17 1/4 mile in a firebird
2 bolt main block
truck heads ( non vortec)
224/224 summit cam
tpi and 2 grand national turbos

thing runs pump gas and is street driven without issues

btw those 4.88 rear gears are going to make it feel like a slug, some 3;73's will make a huge difference alone

ive been on the turbo forums either no one repsond to ur thread or u get a jerk repsonding whole just wants to talk crap... nonetheless im looking for advice as to ideas on why this motor feels lacking not so much on the turbo theres no debate on if an aftermarket set of heads is better than stock i plan to change it would u agree the lower the compression a bit in order to run more boost is a good idea? what do u thiink about copper head gaskets for a boosted motor

Inside I all the nonsensical bickering I'm hearig to change the head... I looked at the world s/r torquer heads I believe they are 195cc int runners with 76cc chambers going back to my questio would u suggest using a thicker head gasket maybe copper in order to lower compression ratio so I can crank up the boost

I'm not gonna start tearing down the block and rotating assembly the changes I'm looking to make are up top if I run a thicker head gasket I should theoretically be able to run a smaller chamber head like a 64cc which is more available and has more choices

Yeah I feel u on that one I believe u said earlier that I should lock the distributor out and set total... Are u suggesting that I try a total and give it the seat of the pants test and add or remove timing from there?

engine will not spin above approx 4000rpm

hey guys i need a little help for the last couplke weeks ive been trying to get my nova to perform ... its a sbc 355 with a stock small block cam stock heads single plane intake manifold powerjection 3 efi msd e curve distributor and a gt45 turbo... since i got it on the road i feel its been way down on power...i was hoping for AT LEAST 500 hp it makes some torque not what i would expect but i was expecting a lot more up top and going down the road ive been pretty scatterbrained trying to check everything out at the same and im fried... my lastest discovery is that with my foot to the floor the car other reaches 4000 rpm it shoots a little above probably because of the inertia of the rotating assembly... obviously something is dropping out... any help is apprecciated
