basically the title explains it all my '87 350 block just came back from the machine shop bored to a 355 and im installing forged crank, h beam rods and forged pistons in it intending to twin turbo it with 20+ psi (yes i know what im getting into). And considering that the roller cam and lifters are so expensive i was wondering if i could just go with a solid cam and lifters.

 

i dont see aproblem going to solid lifters instead of hydraulic but i would definately reccomment sticking with a roller cam

 

If you can afford the machining, and building of that motor, and then twin turboing it, then $100 more for the right cam shouldnt be a problem here

 

Are you talking a solid flat tappet or a solid roller? Both are do-able. Not sure if anyone makes a drop-in solid roller and matching lifters that would be a direct bolt-in to a factory roller block (don't think so) but you can certainly still do it with more effort/expense.

A solid flat tappet is absolutely no problem. You just need a flat tappet timing chain set, remove the factory roller cam retaining plate, correct length flat tappet pushrods, drop the flat tappet lifters into the lifter bores (they look funny sitting WAY down in the deep factory roller lifter bores but they work just fine), take off the the dogbones and spider in the lifter valley and you're good to go.

 

all truck motors were roller blocks without roller cams in them. i'm tossing a solid lifter cam into one into my camaro this year

 

i have to have anti-pump up lifters in my application and the cheapest i can find anti pump up roller lifters is a little shy of 300 combine that with the 250
+ for a new roller cam and it gets to be more than i want to spend right now.

btw im still in high school so money is an issue lol

but anyways what is the difference between the roller timing chain and the flat tappet one? also, are the correct length pushrods just the stock length flat tappet ones or is there a size variance?

thanks, most of my experience has been with roller motors so thats why im a little in the dark in this subject

 

lol still need some answers on this one hopefully asap thanks, brandon
