Thread: Making A Small Block 350 As Fast As It Can Be

Tweet

I have Serious plans to rebuild my 350 and want it to be as fast as it can be but ive heard I should make it a stroker motor and it would be alot quicker but Im not exactly looking to make it quick but want it to be quick while having lots of horsepower I heard making it a stroker but putting in domed pistons would defeat the purpose What Should I Do?

Well, as fast as it can be is open to interpetation. In my neigborhood that means you are ready to spend about $20,000.00 on an engine. Domed pistons raise the compression and make it almost impossible to run the car on pump gas.... A stoker engine has a longer stroke and will produce more torque at a lower rpm.....

yeah I know that but I want both without sacrificing too much of either I want it to be quick also fast

Build a 383 with flat top forged pistons,4340 crank,h-beam rods or really good I-beam rods, some good heads Dart,Afr,etc.Use good parts.Bolt a plate of N20 on it and have some fun.

you mean using the crank from a 383 cause the bore is the same

Are you aware that there is no 383 to get a crank from? Chevy never made a 383. The 383 started with folks using a ground-down 400 crank in a 350 block. Pure hot-rodding initiative. Now, custom cranks are available, as are complete rotating assemblies.

Yep go the 383 way. And for a broad power band and good kick in the pants low end torque you need to install a 671 cam.

A 671 cam?WHAT???

671 as in 671 blower. A performance cam moves more air through an engine. A 671 big cam gets the same and better results.

yes a 671 cam and add some of that NOS gas in the tank too you will need good pistons je .ross and a good bottom end and msl head gaskets .stud the bottom end and heads to better main caps fill 1/2 way with block rock.i would make it a 383 with a long rod buy some 4340 steel rods and crank

I think you might be trying to confuse people.

What size of rod? Also I might reuse the stock heads but plan to rework them would I be able to shave them down to a 64cc chamber or would I have to weld them up, Or do I want to? also plan to port and polish, new valves and springs, already have the roller rockers

What is so much better about making it a stroker (aka 383) other then to just shave the heads get domed pistons ,port and polish? Would it just be Quicker?

See if you can find "Hot to Build Small Block Chevies for Power" by David Vizard. I may have the title wrong but Vizard has several good books with dyno curves in them which compare 350s to 383s at various rpm ranges. The 383 definitely has more low rpm torque and a 327 would favor high rpm HP and as you might expect the 350 is in between for torque. There are other considerations such as the need to run on increasingly poor gas and even thinking ahead to E85. You need to study the options more.
