? about tb's
 

hay i have a fast ? will it hurt a motor id you start off with a 58 mm tb ?? its a lt1 intake i know the 48mm is good till 400-450hp but what if im going over that but not right way???

No it will not hurt but it may not be worth dropping your cash on that now. You will more than likely have to mod your tps sensor so you can adjust it to the correct voltage.

There has been a rumor going around since these cars were new that if you change the TB you'll lose low end torque, but I've never seen anything to support this theory so, if you want, have at it, but I would save your money towards something that would actually help performance. JMO

Also to get the full potential of a 58mm, your intake will need to be ported

i thot i would ask and my heads and intke will be ported as much as i can

ok here how i want to build my motor i got a later 350 roller block HD 4 bolt mains its out of a suburban so its got a forged crank (stock gm),stock truck low cpr pistons,i got a set of modded lt1 heads for a gen one sbc i will do some port work to them and i got a lt1 intake (its off a l99) that will have port work done bye me to i want to build the motor for a supercharger down the road tranny if i can find one in a good price rang will be a lt1 t56 (i have hurd bad things about the ls1 t56) and a beefy 10 bolt , i have most of the chassy work done now ,i want to keep my a/c this is a street car wil be driven every day the only thing is the cross flow can i just to the back with one head going to the other?? i may be posting this over on tgo two this is going in a 1992 chvey camaro rs right now its a v6 that's worked over some but im bored with that now

With an auto trans car, you need to reprogram the trans pressure tables for it.
At a given TPS%, you'll have more airflow and more torque into the trans.

I'd save the money on the tb and put it towards a rear end. No such thing as a "beefy ten bolt". Some make it farther than others but they will all break. Try posting in the SBC section, probably more info there.

sorry i like posting with the ltx guys all ways been a ltx fan hints why i have a ltx top end i couldn't find a short block in delaware of my liking so ill have this odd setup now i have a ? i just looked at this of on ltxtech.com and a guy named 95Formula383lt1 sd this "and 96 and 97 intakes are port matched to the heads, but 93-95 intakes are rectangular ported an don't match the heads" any info on that first time i ever seen that
