Thanks for the advice guys, maybe a kit isn't the way to go. So far I have 4 bolt main 350 short block bored out 0.030.
I bought a bottom end rebuild kit - http://www.summitracing.com/int/part...-300/overview/
And that's it so far.
Ideally I'd like to go for 350hp out of the 350. Any advice on a top end parts list that won't break the bank (ideally the same or less than the Edelbrock kits)?
