another 351w swap question

blk88lx · 12-14-2002, 01:18 PM

Ok, 351W no wild crap inside or extreme head work. what would be better, 28 LB injectors or 30? what size mass air meter and throttle body and finally, how big a fuel pump? Last time I did this the engine was carbed si I'm not to sure what to go with here. It will be a straight street car.

Also, anyway to install this thing without having to go to a cowl hood?

If it's a pretty much stock motor, 19 pound injectors are plenty.

19 will work i would go 24 at least a 155 lph fuel pump 73c&l mass air meter 70 mm throtle body

depends on the manifold but you can drop the motor with solid motor mounts and remove the fire blanket and it can be closr i have a older hood scoop reversed and bolted onto my stock hood.

but with my box set up i could fit it all under a stock hood with maybe a couple of washers under the hood bolts.

Dropping the motor with solid mounts. Wouldn't that make the car vibrate real bad? It will have a gt-40 lower and a cobra upper. I really don't want to pony up the cash for a cowl hood. Will if I have to but don't want to.
