hello my name is jeff and im building a 91 nissan for my weekend toy we have done a lot of work to the truck as for body and stuff it down to about 2100 lbs. im wanting a fater motor the bone stock 150 hp 4 banger ran 11.90 when the truck was still 2900 lbs and im looking to go faster and i know im going to need a motor that has a lot of rpm power up top so i fount a 283 for 20.00 im looking to build it what all should i do to the motor to get it to go faster

so far all i did was clean and cut the crank .10/.10 the motor will need to be bored how far should i go

i know ill need small heads so im looking at maybe some 305 heads

as for the cam, intake and carb im not sure i would like to run 100 shot on it seens it such a high rev motor i thank it would work good

but im open to any ideal to make the motor faster
