newbie question here,sorry, how do you build a 383 without the 400 balancer? Do you just buy a "cheater" smaller one, or is there more to building the engine? Basically, you can't run the strokers on our track....but i know someone who does(small balancer), but he just smiles when i ask him. I'll seach, but i hoped somebody could help...thanks!!

he has his crankshaft internally balanced. it can be costly.

To save a little money, you can also just have the 400 front dampener imbalance moved to the crank. Then, you can use a 350 dampener and a 400 style flywheel. This works unless the tech guys look pretty deep.

the "good" tech guys quit looking for weighted balancers a long time ago. now, if they suspect you of running a
"big 'en", they just puff you. you can make a "big 'en" puff like a small engine, but it's costly......depends on how bad you wanna cheat, lol.

i've never done this personally, you guys know i don't cheat, lol....but my machinist has. he drilled a small hole into the combustion chambers from the ouside of the heads. i think it was close to the spark plug. he tapped the holes to fit a holley jet. he put plugs in the holes while racing. when they asked to puff his engine he would pull the little plug when he pulled the spark plug and s-crewed the appropriate sized holley jet into the head when he installed the puffer into the spark plug hole. it bleeds off air as the engine fills the puffer. the tech guys never figured it out.

you have to test it to see what size jet you need to puff the cubic inch you want the puffer to read. a bigger jet will puff a smaller cubic inch. you MUST test this first....you don't want the puffer to read like you have a model airplane engine in it or they will look a little closer. you don't want them to think you're outrunnin' everyone with a 200 cubic inch engine!

now the cat's outta the bag! i don't recommend this. it's way too much work....like i said....."how bad do you wanna cheat?"

So that's the purpose of the "Only tech inspector will remove spark plug for c.i. check" passage in the rule book. I always wondered about that.

We have a new local track, somebody asked the tech guy how "how to tell if it's a stroker"......he said, "If it's got a big balancer on it"........lol! I was just wondering if you have the crank,rod,pistons internally balanced,is that how you do it?

There are aftermarket "stroker" cranks that already have the proper internal balance weights to be neutral balanced all internal - can run a "stock" 350 flywheel and balancer... The only thing I'd recommend is to get the entire assembly balanced with your pistons/rods - they're usually made "heavy" so balancing is just removing material and not adding it.
