Title sums it up. Am I going to need to worry about messing up my engine? If so, What can I do? I can't do much motor work being 16. My mods are in my sig.

Having 2 bolt mains won't make a difference in any way that you need to care about on a streetable engine.

2 bolts are good up to 400-500 hp and a good 7000 rpm before they give up. Probably not if you always hammer it but occastionally you should be fine.

2-bolt blocks with OEM main bolts are good to 400hp
2-bolt blocks with ARP main studs are good to 550hp ++High Nickel Blocks to 700hp
4-bolt blocks with OEM main bolts are good to 475hp
4-bolt blocks with ARP main studs are good to 700hp
OEM Blocks with Splayed 4-bolt main studs are good to over 950hp
Bowtie blocks with splayed 4-bolts main studs should handle over 1500+hp!

Its gonna take a heller powerfull street engine to make a two bolt main give out. I have seen 650HP street engines running a two bolt main

also found this on there:

Engine RPM plays even a larger factor in determining safe power limits for various block/cap combos.

OEM 2-bolt blocks are good to 6000 rpm.
2-bolts with ARP studs are good to 7000 rpm.
OEM 4-bolt blocks are good to 7200 rpm.
4-bolts with ARP studs are good up to 8500 rpm.
Bowtie or OEM 4-bolt Splayed Studs and cap are good for well over 8500 rpm

Okay,
