I'm trying to figure out about how much hp my motor will make and what the car will run? Its 88 coupe with t5 410 gears, motor I'm building is 351w roller motor with 4340 forged crank I beam rods Ross forged flat top pistons x303 cam roller lifters Holly systemax heads that have been ported by gore and roller rockers intake is typhoon upper and lower with 30 # injetors

I'm new to the site just wondering what she should run I'm planning on spraying a 150 shot on top to

the 4340 is a bit of over kill but not a bad thing the stock crank prepped right will take LARGE amounts of HP without issues. But the rods and the pistons are a good idea. I would also look into a better cam. Maybe some of the new Comp. stuff. with good head work I would think 400 at the flywheel should not be real far off.

right on thanks, do you have an idea what the car might run in the 1/4 with a 150 shot pn it?

Nope.. there is much more to gone fast then just making HP you have to have a balanced combo that hooks and goes stright as well.

This is also not a tech question so next time post it in our general discussion area.

Like ^he said, for 1/4 mile times you will just have to take it to the track. Everything affects what your time will be...the track, the driver, the weather, tires, suspension, rear end, weight, transmission.....EVERYTHING. Some people have said they have hit 12's just with a stock 351 swap so you never know
