uhh - wrong thread, that's the Ross pistons group buy thread . . .
thats what I was saying... if you are pulling the motor you might want to put in some new forged pistons....
oh btw dan if you need any advice on pulling the motor let me know... and for all those vacuum lines pull the bolts holding the assebly to the firewall and take that all off still attached.. it will save you headaches tracing the vacuum lines during install.
If you don't want to spend too much, just do the piston tops and side skirts. This will give you a little more protection against melting your pistons from excessive combustion chamber temperatures.(high EGTs).

You can see a pic of mine on my web page:

Oh. I thought you were posting a link to a swain tech worth it/not worth it thread.
Sorry to be a little OT here, but Matt92VR4, how does your car run with that setup? Any 1/4 mile times, or impressions of the power over stock? Thats almost exactly my plan, as soon as my wallet recovers from dumping 3k into pulling and rebuilding my motor over the next few months.

brainfood: if you have any advice, it would be greatly appreciated. My car is sitting in Jose's garage (amahoser) right now, and we are going to pull the motor out in the next few weeks and send the block off to be bored, honed, fluxed, rods shot peened, crank ground and treated, then, as soon as I can get the cash together for pistons, I'll send them off too so the whole thing can be balanced.

I'm open to any and all suggestions or roadmap opinions on it, but keep in mind I am on as tight a budget as possible (getting a second job just to pay for it, and I already work 55 hours/week).

thats exactley what I am doing when you are ready to pull them motor email me and I will give you some tips... also what sized pistons are you getting for a .050 overbore?
I dont think I am going to since I am spending more money now to overbore the block and get precat eliminators..

I think we are going to pull it out next week. We just have to find a time to use the impact wrench to get the exhaust and stuff off without pissing the neighbors off, can't exactly do that at 11:00pm, you know?

I don't know about the pistons, Jeff Lucius went with Venolia pistons and seems to like them (he had his overbored .050 as well). His site has some great info on pistons, and a list of manufacturers with contact info, so I'm going to shop around a bit I think. I have plenty of time, it going to be a long while before i can afford them anyway (since I now have to make payments on another vehicle).
I was just saying becuase the ross pistons are supposed to be one of the best and it is a good price on them... I think the venoli pistons are great especially becuase they are affordable.
