Thread: 700hp N/A chevy build SB or BB?

Tweet

Hey everyone,

Im tryin to build a solid N/A small block chevy that will only be used on the track. My goal is 700hp and i know that this will be difficult to acheive. Would it be cheaper for me to use a big block? or would i be able to make that much power by stroking and boring the small block out.. maybe a 383? 406? 434?.. i have a daily driver 450hp 525tq chevy 454ci that took me about 6 months to build. its my baby and that power was made easily. i want to try to make alot of power with a small block. i just want to know if it would be better to use a big block and if not how to make all this power with the small block.

any tips and advice will help.. thanks

I like This one . It's a 454 SB Chevy built by World's . It is 600 HP and has 575 ft-Lbs of Torque . BB or SB 12k That kind of HP will Cost You . Look into a Nitrous Build .

N2o......its big bang for the bucks

I agree, cheapest horsepower there is.

you can get a crate chevy 572 720 horse for about 13-15k i belive

i can build and many can build a bbc less then 13.000 that makes around 700hp and more with Nos the small block will need very good parts to push it that far with Nos just how many time are you going to hit the NOs??? NOs is the best bang for the buck but the bang cost alot when you melts the pistons and send your rod thru the block.i wound build to 496-512 with stock block or with a world block 555to565 and build it mild street use small roller cam and 10.5 cr this will make alot of TQ and you will feel that more then hp and if you want more spray it but i do not think you would on the street??

ya im thinkin a bb.... probally 496.. i dont like N0s it does some mean things... i kno i have to go with wide open heads but why a small cam? wouldnt a big cam be better? i want this to be a racing engine for the 1/4 mile strip... shouldnt i go for high hp and tq??

you could get a vortec max at a junkayrd they are already 496 and beef that up

well for the street i say small cam that would be in the 650 lift and 240 dur @050 this will work better then a 750lift and 270 dur @050 for street use if your going just drag racing i would build a 496/512 and still build it to make tq you can make it a hi rpm engine but why? you just will wear out the parts faster

ya wearing out parts is a waste. might as well go the nos route if im going to do that..
