What engine should I build?
 

i have a 350 block, 350 heads, 400 crank, 350 pistons, and 305 h rods. what need to be done to build a proper 383 stroker

messurements on the parts would help!

Get a 383 crank, rods, and pistons.

Grinding a 400 crank to 383 will cost as much or more than a aftermarket. 350 pistons wont work wrong pin hight. best to buy a ready made kit.

Heres a good deal on a rotating assembly for a street engine. http://www.northernautoparts.com/Pro...tModelId=14966
Just have to get it balanced.

Get a set of 400 SBC 5.565" connecting rods. The mains on the crank need to be turned down to the 350 crank size. The 400 crank will need to be re-balanced.

The 350 block will need some hand clearance grinding on the bottoms of the cylinders and the oil pan rail for crank/rod clearance.

i thought a 400 crank in a 350 + 30 over made it a 383??? and that the block had to be machined??

there's a lot i dont know... so just asking questions.

Competition Products in Oshkosh Wis. has excellantprices,sharp phone techs,and free shipping.Lot cheaper than reinventing the wheel,Google them.GEt us the numbers on the block and heads.Just my thoughts.LARRY :) All you need to start is a rotating assembly

i do have a stock 400sbc (as far as i know) and a stock 350 sbc complete. and a set of 305 h rods and pistons stock. i would appreciate some ideas. going in a 1985 pontiac traans am

..........and 5 months later he returns ?????? If you have a complete 400 sbc then just build it into a 406, why spend a lot of money to get a lesser engine? A 406 will chit on a 383 with the same parts.

what do i need to do or get for that 400 to a 406

Have it bored +.030. You'll need .030 oversize pistons.

Yes, but it only means a crank with a 400's stroke of 3.75". You can use an OEM 400 crank but need to resize the journals to 350 specs.

is there any more suggestions on that 406 or how to keep that engine cool that those engines are known for. would getting it internally balanced do any good or should i leave that part alone. anything helps thanks

my 400sbc has never overheated. Its a myth.
