Rotating Mass Queistion ?
I Have Herd That A Stroked Engine Can Not Rev Out As High As Non Stroked Engine
Something About The Larger Crankshaft And Longer Rods Mass Is Larger And Puts More Strain On Engine
I Have Idea To Use Say A 350 Block And Maybe A 327 Crank And Steel Rods Forge Al Pistons To Try To Get A Higher Reving Engine
Any Ideas About This

A 350 block and 327 crank gives you a 327 both have a 4 inch bore.

I use a 400 combine with the stroke of a 327. This lets you mount some very long rods in it (6.250) which will give a better rod/stroke ratio and reduce the weight of the pistons. This in turn will give you the opportunity to reduce counterweights on the crank. If you have them turned in a lathe for proper weight, you also reduce windage.

i saw an artical o th e 1967 z28 with a 302 chevy
i think the chevy 302 used a smaller crank maybe a 327 block and 283 crank
in the artical the engine could rev out to 7000 rpm
why am i asking about this because i like th esound of a screaming chevy

400 block 302 crank 358ish cubic inches with a very short stroke.

A Nascar engine is basically this.

You are going to need some high flowing heads and an expensive bottom end.

So What Block ,crank ,bore,rods And Pistons Would I Need To Get 302 Of Displacement
350 327 Have Same Stroke But Different Bores Or Am I Thinking Wrong
Explain How The Need For Speed Buzz Bombs Make All That Hp With A 4 Cyl
Lots Of Boost And Revs Wright

A 283 crank and 327 block will give you 302ci. 350 and 327 both have 4" bores.

I Got Read Closer 350 327 Same Bore Different Stroke
If Bore Is Ame And Stroke Different Then Displacement Should Be Different
Smaller Crank Lighter Rods And Pistons Maybe Al Fly Whee,high Flow Heads ,roller Cam,roller Rockers Goos Set Valve Springs Means Higher Revs
What Do You Guys Thank

a 400 with 327 is 347 ci.

Nascar employs I believe a 3.30 inch stroke. This however puts you in a odd combo where no readily parts are available for thus more expensive.

I can rev even higher than 7000 but above cam and induction gets critical.

Essentially cutting weight on the piston reduce much more the bob weight than does the rod.

You would have parts availability/expense issues with used UEM parts. I believe all 327 cranks are small journal which leaves you with specialty aftermarket or a lot a machine work on you combination.

There are large journal 327 cranks-that was what was in the 307's. 327 crank and 283 bore. So we all no how that doesn't work real well.

The NASCAR 358 inch engines LIVE AT 9000+RPM and are still making power at that RPM. The Z-28 had a 4 inch bore and 3 inch stroke. So the 350 block with 4-bolt mains can be used to make a 302 engine. Dave Strickler's Old Reliable Z-28 with a 302 had SHIFT POINTS of 8200 RPM. So it certainly would rev beyond that. The 301 inch engines that were made from 283 Chevys back in the late 50s were VERY popular with hot rodders, but their life expectancy wasn't very good. 2-bolt mains and none of the parts went through the special preparations that the factory did with the 302 Z-28 motors. So they tended to come apart fairly often in a spectacular way :D
