    twisted wedge,xe282,dss piston?

    TWs require relocated valve reliefs. As long as you have the DSS pistons with TW valve reliefs, you'll be fine. But, as others said, check it anyway. Every motor is different so you never know for sure until you check.

    Do your DSS pistons have valve reliefs for TWs?

    Idle problems/stalling since 30lb injector swap

    IMO, the Pro-M 80 is a much better meter than the C&L 76 or the Pro-M 75.

    proper break in period

    No. Roller cams don't require a break in.

    Do I need a battery cut-off switch?

    Even on test and tune nights, NHRA certified tracks are required to tech to NHRA rules. Not all of them do it of course. But, if you race at a track that techs to NHRA rules, you must have a cutoff switch with a relocated battery.

    Got detonation issues w/ 331, could it be my 30's near their max???

    30s should be fine at that power level. What's your compression ratio?

    Idle problems/stalling since 30lb injector swap

    It's actually really easy. You'd be surprised.

    proper break in period

    Rings seat very quickly or they don't seat at all. The first wot throttle pull after the oil change will seat the rings.

    proper break in period

    Roller cam motors don't need a break in period. Start it and run it for 10 minutes or so then change the oil. Now go beat the piss out of it.

    Idle problems/stalling since 30lb injector swap

    Was your chipped burned on a dyno? It sounds like your chip guy doesn't know what he's doing. For that $600 you could have bought a Tweecer and a cheap laptop and tuned it yourself. Hindsight is a bitch huh? :damnit: Four years ago I ran 30s on a motor very similar to yours with just a...

    Tire pressure for nitto DR's?

    Here's a shot of my car launching on BFG DRs. This is a 1.58 60' launch. These tires REALLY work if you use them right.

    Tire pressure for nitto DR's?

    I ran 11-12 psi in 245/50-16 Nitto DRs four years ago and got consistent low to mid 1.7s in a mid to high 12 second car. Now I run 10-11 psi in my 275/50-15 BFG DRs and get consistent high 1.5s and low 1.6s. They are VERY stable at 115+ mph trap speeds. FAR more stable than a bias ply tire...

    Tire pressure for nitto DR's?

    Exactly. 11-12 psi and big burnouts.

    (Nitto) Drag radials out back, but up front too?

    DRs have a soft sidewall and aren't made for handling. Really dumb to put them up front IMO.

    Nitto 555s or 555Rs?

    Regular Nitto 555s are just a cheap street tire. Nothing special about them. I would use Comp TA ZRs before 555s. 555Rs are a totally different animal. They're a great street strip tire. Nitto has done a great job of marketing by using the 555R DRs to increase the reputation of the rest...

    1.6 or 1.7 rockers?

    Feel better now that you've made a fool out of yourself? :rolleyes:

    1.6 or 1.7 rockers?

    Do you guys ever read the previous replys before typing yours? :rolleyes: What you're saying doesn't work. Read Michael Younts post above for an explanation.

    65 or 70 TB for my setup?

    IMO, the 70mm Accufab is your best choice. The Performer intake is matched to a 70mm tb.

    Post your rwhp/rwtq

    My little NA 306 made 365 rwhp and 353 rwtq a year ago. Since then I've switched to 3" exhaust and it picked up trap speed so it's probably over 370 rwhp now. TEA ported TWs, Holley intake, and an FTI cam.
