Now i am assuming the bigger the better when it comes to stroke

However which one of these would be the best????

I mean if i am going ahead and spending 3300 on a shortblock 355 then whats another 200 for a 396 instead??? (makes sense to me)

these will have the LE3 H/C package on them

would just more torque be what i was looking at? i would like 450na and a strong built bottom end for maybe a little juice 75-100 just to put me over 500whp

I'd go 383. No sense in going bigger on stock heads IMO.

 

le3 h/c pack would be going on it

 

I mean stock castings.

 

i wondered after i posted that if thats what u were refering too.


what kind of heads would u need for a 396 if the le3's arent big enough

 

I would have htought LE3 heads would be fine. It is only a 13 CI difference. The bore is the same, so its not like you could go with bigger valves with a 396 than a 383.

I havent been real up to date with whose heads flow what, but AFR makes some nice numbers with their LT4 head packages. Their numbers used to be exaderated a little bit on the intake side. Everyone I seen who had their AFR heads flowed pretty much came up 4 to 5 CFM less on the intake side than what the heads were rated. And, suprisinginly, they flowed several CFM MORE on the exhaust side with some of their more hogged out sets of heads. AFR makes a good product. I havent seen much about LE's head but the little i have heard, their supposed to be pretty damn good numbers. Not enough to warrent spending thousand of dollars for a few CFMs more. After all, you are going to spray on it too. If it was just a NA high winding engine, then I could see it, but in your case, I think the LE3s are fine for what you need.

Give them both a call though, talk to them, see what they think. Theres alot of good advice on this board from experienced engine builders. See what they think about it.

 

yeah my plans were to call them when it came time to break out the money and what not.

this is just the tip of the ice berg, questions here and there.......guestimate pricing, thoughts and what not.

i feel the same way u do though i dont see how 13 more cubes could make a difference in head selection.

i pretty much think i want a 396 with the LE3's........then a 75-100 shot for fun.
