hello there . well i just got $10,000 from the insurence from a car crash. definlty not worth it . crushed both ankles and my crushed L4 vertibra. any ways i was going to decide what to put in my 70 chevelle. i have a sb 350 right now with few mods. i dont no to rebuild it and put a single or twin turbo on it but still gas friendly. or to put a 454 and it comes with the trans for 2500. runs and every thing comes out of a wrecked r.v. if i got the bb i was going to put a cam, new alum heads mini blower and may be a roller cam.
i dont just want to blow the money i only want to spend about 5,000. or less . will the r,v hold out on the bottom end with alum heads and a mini blower. but can i build a 355 with over 500 hp and torqe thats is pump gas.
but i would love to say that i have a bb, cause most hottrodders have a sb there not bad but i think it would be cooler if it had a bb. but then i would really love a sb twin tubos .love that sound. but the ultimate thing is the big block with a turbo but i cant find any kits for them there all for sb. do you know any sites for bb tubo kits???? what r your thoughts????????

I would probably go with the big block. Parts are stronger, and it will be way cheaper than upgrading your current to setup handle the power and then adding the turbos. I dont have a whole lot of time right now, but I have a couple of ideas. You can get 500-550 hp out of a big block with a set of ported oval port heads and keep it streetable.

s.b.'s are cheaper to build than b.b's. but if i had that kind of money to start with i'd build a very durable sbc,your choice,but only spend money where it had to do with durability so you could thump on the motor but not hurt it.then put it in a monza.big power in small car equalls lots of fun.by the way i know how you feel about your back.mines between L-4 & L-5 and i have an infusion pump in my right side i have to go in and have it filled every 6-8 wks.it doesn't get better.

I agree with Firestone... Also want to point out this is a Chevelle so we are in the high 3000lb to low 4000lb class so torque becomes a must... Also with factory BBC parts which are not that expensive and will make huge HP and torque plus highly reliable then it does make sense to go BBC...

BIG BLOCK FOR BIG CAR! Hg

well i thought about it and i am going with small block. for now. i already have a 350 with a came and intake so i am going to put sports man ll heads on it. expecting about 420 hp. thats pretty good for the street. and i am going to put in a 700r4 with a 2200 stall.rated to handle 650 hp. then in a couple of months when i can walk normal with out cruches i will fix up a nove that i have.put my 350 in there and a th350 and sell it. then take that money and buy a bad ***** 502 with alum heads and mini blower . makes about 610 hp and 700 tq. thats plently enough for me. so thanks for your guys thought about a set up!!!!! I an going have lots of fun terring up those rice eators!!

Keep in mind that most of the money that you put into your current motor you will not get out when you sell it. I would save your money, or build what you want right now. Dont throw money away.
