What type of 4.000 crank/rods would you recommend for a L98?

I'm sure you know where I'm going with this :thumbsup3:

Ive been checkin out Summit (I get all my goodies from there) andl I see are Eagle, Scat & Howards, and others just wanted to know if anybody has a personal interest?

Intended Hp /rpm of the build and your budget?
You can pay $600 or $2500 for a 4.00" crank depending on your requirements

Just looking to build alot of torque down low, I figured a larger discplacement would be a good start

stroking to 383 will help with that...those are all good brands...I have all Scat Forged components and a big Howards Racing, Roller Cam in my 383/525HP...but like OZ says, it just depends on what your power goals and budget are

Ok so with a longer stroke what size connecting rods will I be needing and or pushrods? ( i think)

What block are you planning on using?
3.75 (383) is most common stoker ; minimal clearance work of block needed and stroker parts common and cheap .
3.875" (396 ) requires more work
Even the 400 SBC only had a 3.75" stroke.
Plenty of online info if you use Google

Thanks for the link vetteoz im planning to use my stock block, im looking into buying a stroker kit but not sure of what it is ill need exactly

Aside from the crank. Can the stock heads and injectors handle the job?

If you are planning a big cube SBC with stock heads heading you are thinking in the wrong direction.
Better to build a 3.750 stroke 383.

At 406+ cubes ( 4.00" stroke ) you are going to want some big heads , prob 200 cc or better if you want it to see it's potential.
And you will need larger injector and prob a better intake than a TPI so it can breath.The TPI was designed for a 305

If you read the write ups , you will see a 4" bore x 4" stroke SBC is not a recommended build because of the amount of work
and cost involved vs easier/ cheaper ways of making the same Hp
is usual have the bore larger than the stroke if you want the engine to rev; 400 SBC was 4.125 bore x 3.750 stroke

Whats your budget and expected use (Hp / revs). Do you need forged parts?

Stroker kits start from $770 with a cast steel crank ,I beam rods and Hyper pistons

if you want forged pistons and crank then you are looking at $1000+

if you are shooting for 400 + Horsepower, go all forged and be safe
