So I have been doing some research for my 340 and its going well. But like always, I want your guys input as you have never took me down the wrong path!

Looking into doing a stroker kit on the 340.

I think I want to go with the SCAT stroker kit but I want another opinion! Looking to go for the 408/416

Thinking 1.6:1 roller rockers? Anyone using these and are they good or bad

Any ideas about this kit/ better kits to buy?

Wanna make about 500 h.p out of this puppy and need some more well rounded guidance.

Also should I go with a Forged crank or stick with cast?

Then its onto pistons...Flat top? I know this is alot to ask, but just got a new motor to play with and I have never fully built a engine.

Thanks guys~ Sean

 

HP is in the cam and heads.Torque is in the stroke. What is this engine going to do? Scream at high RPM or grunt out stump pulling torque at 1800?

 

I would go with this forged internally balanced Callies stroker kit from Mancini.

500 hp! don't even think about a cast crank. The Mancini kit is a proven combo. along with a 7-8 qt Milidon oil pan Some ARP main studs maybe a windage tray You may need to shim it away from the crank for the stroker clearance

 

@bigblock

I want to get the horsepower at the mid to top end.

@TVLynn @Bremereric

I will definitely look into the Mancini kit and thanks for the advice!

Here is the new canvas, 1971 engine with J heads

 

Do I have to do a stroker kit to make the kind of power I am looking for??
