Le Set up....
well either way Id have the cost to clearance the crank as the difference between the two in prices.. If your going for the setup to get you down the track the fastest.. Either of them would have spray..

I think a good le3 355 can go 10's though on the motor IF setup correctly.
stroke that puppy The only time its not so good to stroke a motor when rpms and how fast it can climb are a major consideration like a turbo car. Ultimately I beleive it will make more power over a 355 but people seem to trend toward those set ups.
I say still stroke it.

Is that 10's n/a keeping away from upgrading to a new computer cause the rpm you'll be running? I dont not want to throw $2300 in a xfi or dfi computer.. And those heads flow 295 cfm..
