Hey guys,

I figured I'd post over in this section as well as FI to see what you all recommend.

I'm interested in upgrading my current budget short block to something that can reliably handle ~700RWHP via 76mm turbo (say 6,500 rpm limit). I'd like to avoid a $4,500 shortblock if at all possible at this level.

CURRENT:
Stock crank/rods, 4.000 SRP's and ARP fasteners.

I'm half tempted to swap out my stock rods for some decent 5.7 H-beams, stud the two bolt main, and re-use my current std. bore dished SRP's. Looks like cost for this type of DIY job would be $1200-1500. Not sure what the current leakage is with the stock 35K mile std bore though. If it ends up needing to be bored with new pistons that could change the scope here.

Do you think that'll get the job done?

I've been bouncing back and forth with the idea of the above 'budget' forged rod motor or purchasing a complete splayed main, Callies SB in the ~$4K range.

Would be going into a street car with as much as I can get out of a single TC76mm and pump gas. Mild heads and cam.

Help talk some sense into me

Thanks,
Scott.

You want everything forged. Thats too much power not too.

Your stock crank and studed mains setup could last but it would be iffy and you would be pist off if it went after just finishing it. I would suck it up and spend the money on quality parts.
