XD_351

Hey people, need some info on who or where i can get a decent set of slugs for my 351. I would like to keep to a minimum when it comes to $$$ but if this cant be avoided so be. It doesnt ever see more than 12 psi so Hypers should be fine, but not sure if i can get the comp i want (8:1-9:1). I have 2v O/C Heads and standard rods. Any ideas on how to achieve this would be .

At least it hasnt seen 12PSI yet. Once comp is down and its all run in again, i am going to boost it up!!

Thats roughly a standard 351 comp ratio. Minimise skimming the heads and decking the block.

Could get 20cc dished pistons (not sure on brand availability & $$), which effectively increases the total CC size. So with 65CC chambers, 30thou overbore, 40thou gaskits, ~25thou deck height you'd be looking at about 8.5:1

As above with 70CC chambers = about 8:1

With flat top pistons you'd go to 10+ (roughly 2 points up)

Go forged and do it once. Did you melt the piston.

No melting, just an extra large valve relief installed with out my authorisation!!! Dont know what caused it but the pushrod in number 1 exh has about a 30 deg bend. No relation to piston, was number 4 with the fancy internal machine work. ALL CAUSING AN EXPENSIVE REBUILD, which unfortunately got bigger and bigger. Not to mention the extra $$.

Stuff the pistons, i have just been informed the cast quality of clevo cast headers are not up to the task. The j pipe setup used will now be thrown to the hills and a new tubular manifold made. After another heap of coin, we will have one more prob sorted.

Always the way. In the end it usually works out to be more appropriate option anyway.
