Baby Stroker
 
I am in the process of building a little stroker engine...This is a 316 sb chevy...4.030 bore w/3.1 in stroke crank...going to use 6.2 rods...this is just an experiment as I have all these parts lying around...took a stock 262 crank and had it cryoed...going to run some 2.02/1.6 492 heads on the thing with a tunnel ram/weird injection setup...has anyone done one of these weird combo's before? Thanks...and yeah...I know it is a small one..just wanted to try it and see.

Never ran one, but I've seen one run.

Guy here in St. Louis had one years ago, backed with a 4-speed Lenco.

He launched it like 8500 and shifted around 11k (or so he said, and it surely sounded like it too).

It ran like a scalded dog.

It was in a full tube chassis 67 Camaro... I seem to remember mid 8s?

But, it did have a set of aluminum heads, although I'm not sure which.

Had a friend 20 yrs. ago running a 288" Nickens motor in a 2350lb X ProStock car, but with alum heads and 2 660 carbs, would run 8.80@163 all day long. comming out petal on the metal and shifting a lenco @ 9500. Real impressive car in it's day.

Zip.

This will be in a 1600 lb limited pavement sprint car on alky....

i think gm did -(in a way)--- 283/ 327,--- high rpm motors-
kinda like a import (sowing machine)-

performance is performance-- "as long as i get there first,and faster"
:twisted:

I ran a 304 which is a destroked 350 block, 283 crank , bored .030,, I also bluw up a 296 at 13000 rpm, I had a 12000 tach and it went above that, so13000 ! I swear to god above on this!!!!!!!!!!!! This was years ago, in comp. eliminator.

sds10racer 01-29-2008 09:13 PM

i ran one of those 304 too. about '79 to '81. high revving thing.

Well...I don't want to run 11-13 thousand rpm!...But I have a set of motown 220's with a 54 cc chamber...would this help in the upper rpm range? We usually exit the turns running 3500-3800---- this is a flat top engine at this time ...but I have some 12.5-1 domes lying around I could use....we only run 10-12 times a year....so will get torn down after the season.....

if your staying under 7k rpm, why not keep it a 350? your just loosing tq by de-stroking it.

When you're letting off going into the corner, whats the RPM?

Can you adjust gearing to increase the RPM a little higher?

Small motors tolerate higher rpm, big motors don't. Ever seen a F1 engine? They rev those to about 18k.

poncholvr 01-30-2008 04:18 PM

just lighten ,and balance a 350,use good stuff- and it should handle the rpms ,
formula 1- definately----lol

sprint3 01-30-2008 05:05 PM

top rpm for our 350 is around 6800-7000 when we enter the turn ..let it coast through a little and back on the gas...don't use much brake...Have not run the mini-stroker yet...going together in about a month...this is just a project for me as I like stuff out of the norm(I also have an 18" offset supermodified with a 36 degree layover). So was just trying to get a little input about this combo...thought with the 6.2 long rods..may help a little on the bottom end deal....
