Stock Stroke+5.4" Rod= Hard To Find Pistons

I have a R304ci longrod with a 3.0 stroke crank and 5.4 rods. Their is a better piston to rod ratio but the only real reason IMO to do a longrod is u don't have to change the rods again when u stroke it, just change the crank stroke and pistons. For ur 5.4 rod I would do a Scat 4340 H-beam with the ARP 2000 rod bolt upgrade.

SRP makes a great piston but if motor is going to stay NA I would find a piston w/ 11:1 comp, still will run on pump gas. u could try Probe, Ross, CP, or BME for pistons. Sealed Power file fit ring set, plasma moly first, cast iron second, stainless steel third.

I would do either the stud mount AFR 185's or the TW cnd 185's from Summit, RPM ll intake port matched and a Comp Cam XE282HR and go with ceramic coated LT's last a lifetime and look awesome, Dr. Gas X-pipe 3 by 3 and a Magnaflow exhaust. Sounds like a Ferrari on steriods. Should hit 350/350 @ the RW easily. There have been 306's that have hit 385rwhp, sometimes as much as 331/347 strokers. It's all in the how well the combo was put together and the tune.
