Default Lt1 355 forged pistons?

As the title states Im looking to do a 355 build with forged flat tops ONLY because the budget is real low. So can someone give me part numbers for a mahle piston that will allow LLoyd Elliot heads and cam. Also Im looking for part numbers on the splayed 4 bolt main caps and arp bolts.
Arp rod bolts #
mahle piston # or better yet a lightweight piston #

thanks, Tom

if you're on a budget why are you converting to 4 bolt main?

a 2 bolt will be fine.. My buddy is spraying a 250 on a 2 bolt motor going 8s. Granted, it's a ford.

people definately underestimate the 2 bolt mains. honestly the money spent on that could get you a nice 3.75" crank prolly

Rod Bolts
113-134-6005 ARP High-Performance LT1/LT4 Connecting Rod Bolts for Powdered Metal Rods $62.99 (Thunderracing.com)

Main Bolts (not sure which is right but imagine you need the "splayed" version)
113-234-5602 ARP SBC Main Stud Kit 4-Bolt Main, Large Journal with Straps & Splayed Caps $82.99 (Thunderracing.com)
113-234-5601 ARP SBC Main Stud Kit 4-Bolt Main, Large Journal with Windage Tray $94.99 (Thunderracing.com)

if you want to locate the parts on summit's website just take off the 113- part at the beginning of the p/n

and people understimate the stock crank, I was just shy of 900 crank on a stock crank with no problem, others have made a lot also(300+ shots).

If you want a real budget, use the stock rod and trw piston on a stock bore(assuming you have a good block) and just hone it. Stock main bolts, stock rod bolts, new bearings/rings, cheap budget shortblock. Just make sure to get a good balance job.

nah wasn't trying to downplay the stock crank, it's a great piece. just saying if he has the money to blow on a 4 bolt main he could get a decent 3.75" stroke crank in there just as an example of the kind of money he's looking to spend on something that's unneccessary
