I have a 1969 351w and was planning to do a master rebuilt, but was wondering if a 393( just adding 302 pistons and a differnt crank) would be "better" than a master rebuild?

and con's
of this cheap 393 stroker setup?buy a decent one like chp at the least, some of the cheap kits like on ebay will sometimes cost so much to balance you could have bought a decent kit.
chp kits can be had for 900.00 b ut compression will be high, you can get a good scat kit for around 1100.00, with everything. At least use a good crank.......

A stroker kit a way out of my budget
. Thats why I'm debating on either getting a master rebuild or build the 393(302 pistons and different crank.)
*try'n to get 400hp+*
-What should I do for a daily driver?

if you only want 400hp, then you can build a nice stock stroke 351w to do that. a cheap 393 will give you some monster torque though. check this site out for an inexpensive crank;

The only time a 393 was "cheap" was when there were no aftermarket cranks, rods and pistons. Soo many guys run into this very problem you will have. It will cost 200-400 to balance the "cheap" 393 when using an aftermarket crank, stock rod and 302ch piston. Then 99% opf the time the piston skirt has a good chance of hitting the crank counterweights. You are money ahead doing a 408, they balance with no heavy metal needed and bolt together, the old "cheap" 393 days are gone. Do a rebuild on your 351 and call it good.

actually the 408 was the earliest stroker crank for a 351w engine. it still needed a lot of work cutting down the counterweights, and a custom piston. the 393 is a custom crank, and if oyu follow the links that ratio and i put up you will find the cranks, ready to go, are $270 plus shipping. and since you reuse the stock 351w rod, and off the shelf 302 pistons, you can build a nice stroker for the street that makes good power, and if you can assemble the engine yourself for less than the cost of a stroker kit rotating assembly.

I think I'm just going to build the 393 (crank and pistons ) because I'm only trying to make really good street power.
- So I already know I'm going to buy a SCAT 393 crank. What kind of 302 pistons would you guys recommend? And, do I just use my stock rods?

Couple things, first I own those links
secondly, the 393 is one of the earliest strokers before any aftermarket. Take a stock 3.50 windsor crank, offset ground to 3.850, use a 5.956 windsor rod with a 302 piston, this is 15 years ago bud. Again the problem with the majority of 393's is they take 3-5 slugs of mallory metal to balance to 28 which is anywhere from 200-400+ dollars just for balance, then most guys trying to build a 393 on the cheap buy the cheapest 302 pistons and the skirts are too long thus necessitating you mill the piston skirt, been there done that in the 90's. The 408 is a youngin'

You don't make sense...
How can you offset grind that large an amount of stroke and still use stock rods?
Don't work.
Also, the 408 is from the 70s bud.
Got news for ya.
It started as a 400m crank that was trimmed to fit a 351w block.
It is almost (not quite) a drop in affair.
Then, offset grind that, combine Mopar rods, and you get even more cubes.
A buddy of mine built a 427w using this method.
We are not talking about offset ground cranks and mallory metal here.
The cranks in the link are custom cast and very close to neutral on balancing.
They are not made from stock cranks like you hint.

I think Im just going to go with a rebuilt 351, because if I cant build a stroker rite, why do it right! but can you guys help with some good set-up on the new thread.
The link is MY store bud, they are not even close to neutral balanceYou don't make sense...

I will leave it to the know it all's now.ratio is right about the 408 being from the 70's. joe sherman was building 408's for drag racing in the late 70's and early 80's using the 400 crank, because it was easy to build. he used stock rod lengths and chevy 350 pistons to make things work out real nice. as for your cranks and needing to be balanced, i was wondering how you could sell a crank like you have, even a cast one, as cheap as you do. not a big deal though, just part of the balance job.

I don't know it all, but you sure don't either!
Think you can turn down a throw to gain .350" stroke and still use stock rod?!?
Never heard of a 351 stroker before the 90s?!?
Think 408s are younger than 15 years?!?
If that really is your store, I'll be sure not to buy there.
I like folks that are experienced.
You have not shown that to me.
actually ratio you might cut him some slack. the only stroker engines that were popular before the late 80's was the small block chevy, and the other various gm brands because they were easy to do. remember that putting a 400 chevy crank into a 350 block you only need turn the mains down about .200", and putting a 350 crank into a 400 block you use bearing spacers. the other gm divisions did much the same thing with their engines. another popular stroker is to take a 427fe block and pop in a 428 crank and get 454ci, or pop a 428 crank into a 390 block and get 410ci. also remember that the 351w was not a popular engine to build until the late 80's either.
