350 pistons

[LTb1ow]

This may be a dumb question, but I cannot seem to find a set of forged 350 4.000 bore pistons. They all seem to be for .30 over applications. Am I just not looking hard enough?

[camaroAL]

u can order them std. bore , they just sometimes dont list em'

[LTb1ow]

I have been looking almost everywhere, I guess I need to call places?

[camaroAL]

yes sir. just call, they got em... which ones u looking at? sealed power makes a good cheap set.

[LTb1ow]

I was looking at JE/Mahle

[camaroAL]

ohhh, u want top of the line do u...lol

JE non coated ftw!!!!

[camaroAL]

je is a great choice, but getting back to ur build, ur using a stock crank and block. which will only support so much power before u crack the crank or block. that being said, u can save yourself a bit of cash and still be able to reach ur goals, such as sealed power forged pistons and an sir style rod. if u were going to use a good non cast crank, id say je pistons and a set of killer rods, if the block sonics well enough!!! if u are looking for 500-550hp u dont need such high dollar components. just my suggestions not orders...lol..

[LTb1ow]

Perhaps, I am just not wanting to have to clean up the track when the engine pukes the crappy pistons.
These are the rods I am looking at,

with Hypereutectic Pistons u can only spray around 75hp worth of spray.
for those that may have wanted to know...lol

Nah, people spray more than that, I have seen up to 150 shots on stock setups. Now how long do they last, I doubt very long, but its doable.

75hp is the safe # , if u want longevity
its bad enough when u use the right components for nos and ur tune is off u can hurt ur engine. but to go more than 75 on a hyper and have a bad tune, its lights out!!!!!!!

[LTb1ow]

Yea, I am just looking for something mid road that will take a hopeful 150 shot and maybe some boost later on.

[camaroAL]

small ? how come u dont optimize ur build and just make around 500 or so all motor? its less strain on everything and more impressive.. and this is coming from someone addicted to nos, believe me!!!

500 or some all motor would be great but that comes with a much bigger price tag and truthfully, I just can't afford that.

what power level did u want to achieve?

[LTb1ow]

Well I have no real defined power goal, I want to make a tough LT1 that can take the 150 shot no problem. And last. Thats the goal.

[camaroAL]

are u going custom cam or shelf?

[LTb1ow]

Its a custom now, but I may swap it out, not sure yet. Its a sucky cam for boost/juice with like 13 degrees of overlap so maybe get something with a bit less overlap and more optimized for juice.

[camaroAL]

with the right cam and finesse of ur heads u could make some really good power. and cost wouldnt be that intense.

[LTb1ow]

Well as of now the heads and cam are matched for the max power they can make, redlining at about 6200.

matched for max power? have the heads been put on the bench and flowed? any bowl work? porting? larger valves? comp valve job?

how are they maxed? i bet there is plenty left to do to the heads and i bet ur cam and spring setup can aso be greatly improved. im not being a smart ass btw, im not that good at comp conversation so bear wit me

[LTb1ow]

Ported by Lloyd Elliot and cam by Bret Bauer. Springs are PACs.

[camaroAL]

do they still use stock valve sizes? what does this make as of now at the wheels?

[LTb1ow]

Manley 2.00/1.56 6000 series valves
PAC 1218 bee hive springs (145 lbs seat and 340 lbs open)
Steel retainers and locks
205 cc intake port
flow about 275/190 CFM
