is there a big difference in HP or reliability between the 2? car will see the occasional drag, but mostly street driving (not daily though)

hows the revability of either of these strokers?

 

427 i think you'll need an aftermarket block

 

I love my 408....although with this latest rebuild, I am going a little bigger....415 FTW.

 

Not true, stock block is fine, BUT you need to watch as the rod gets farther into the cam tunnel and may need to clearance a few rods to clear a few cam lobes, depending on camshaft and timing

 

what is the difference in hp between the 2? How much would a decent 408 make? (assuming aftermarket heads cam intake etc)

 

500-600, do a 408

 

^^^^^exactly!! which will be my next power plant

 

is a 408 a stroked 351? or like a bored 390?

 

I have a 427 shortblock now fresh from machine shop just sitting on the stand. Was going to put it in my 95. but looks like having to find a place to live is gonna put that car on hault. PM me if u might be interested.
