Default Info on New 402??

Hello,

Well my stocker bottom end let me down yesterday. Blew a hole out of the oil pan. Now the car is going to be laid up for a few months and I am starting research on new engines.

I am want to go with a short block 402 Ls2 and I was wondering what everyones thoughts were. I was wondering where the best place to get one from is? who has the best specials? what people that have them have to say about the motor? What combos w/ heads and cam were people doing and the outcomes. I was wondering if the stock heads and cam and everything will go back on to one.( I know it wont be using the motor efficently, but atleast then it can be running again while I then save up cash for a head and cam kit) Finally what numbers are people that have them putting down.( Hp wise )


Basically just looking for as much input as possible. Thanks in advance for the help.

Typically best to hone an LS2 block to 4.005" to set your piston/wall clearance properly, this give you 403ci. Diamond has a good flat top shelf piston for 403 build.

Drop me an email if you would like a quote?

Mine did the same thing about a month and a half ago. Except mine took out the block too. It sucks, but join the club.

There's a wealth of information about different 402 setups. Try using Search (assuming it works). Strokers are expensive, especially when taken in consideration the necessary supporting hardware needed for a stout setup. There is no cheap and easy way when doing a stroker. Don't even waste your time throwing stock heads and cam on a stroker short block, it's simply not worth the hassle. If you're looking just to get the car back on the road look for a good used shortblock.

I wish I knew. I am trying to find out as much as possible. As far as the set up I am prepared for what it will take, and I am planning on a large cam. But as far as the heads, I was just going to have mine ported and polished, for a month or so until i could afford better ones.
