Granted they are cool as fuck but his SR71 heads are damn near as good without the Boss look and commensurate price. A 600+ inch Ford with those heads on pump gas should be right there with the Chevy crate offering in performance and price. |

Quote HistoryQuoted: "According to Chevrolet Performance, a single example of the ZZ632 endured over 200 simulated drag-racing passes on a dynamometer during development." "A single example" did the rest of them blow up but one made it? 200 "drag racing passes"? what? 200 8 second max throttle loads? Let me know when it does a 24 hrs of Lemans simulated pass. Chevy would have to get the pipeline terminated at their test facility to be able to keep the motor running wide open for a day. |

Quote HistoryQuoted: It runs on 93 octane. With good timing management and fuel delivery, 12.1 compression and 93 octane isnt out of the question. Quote HistoryQuoted: Quoted: It’s pretty rad. I bet it’s not really a street motor tho. Probly got 13.1 or so compression so pump gas is out. I got a 548 with 1000hp but it’s 14.5-1 and runs on 112 octane at the minimum. Just bought a 5 gallon can of gas to move it around the garage and it was 81 bucks. Drive it to a car shows every now and then and it get 2.8mpg if I keep my foot out of it. Haha It runs on 93 octane. With good timing management and fuel delivery, 12.1 compression and 93 octane isnt out of the question. Don't tell everyone !!!!  There is nothing like the sound of 12/1 at 7500 rpm. Well maybe 12/1 at 8500 (coming soon).  |

A 5.3 or 6.0 can certainly make 1000 plus peak power, but it will not have the off idle instant response and torque of a 10.3. Why do you think those little 5.3’s take forever to build boost before they bump in at the drag strip? Not needed with a 10.3 just roll in at idle and you’re ready to go.

Quote HistoryI'm ordering a set of Higgins CNC'd heads just before Thanksgiving. I'm also ordering the matching intake. I haven't finalized it yet but I'd love to send the heads to Tom at 3V Performance and have him do the valvetrain setup on the Spintron. I've seen what he can do with crazy lifts and super light valve spring pressures. Like .900+ lift and 130lbs on the seat with less than 500 over the nose. Most people are just to fucking cheap to pay for the Spintron time. Because everyone needs an 750+(or more) rear wheel horsepower pump gas street car that weighs 2400lbs, right ???? Right??? |

If that is the case then makes more sense. 8-12k seems to be the range of crate engines that are in the likes of warmed over production car engines. If the Chevy 632 is 20k it is still a good value but reasonable expectation. |

As an FYI...I'm currently at 550ish RWHP as of last Saturdays dyno session. I was the highest HP 93 octane car out of roughly 40 various vehicles for his annual dyno day. I actually made more power than a couple of turbo cars. This has been a 22 year slog with my Cobra. About the only original engine part are the heavily ported Victor Jr heads from the first engine. |

That sounds like some fun for an experienced driver in the right vehicle.
But probably not for the average numb nuts flat billed hat wearing douche. I'm not a SME but I recall an acquaintance talking about his 600+ HP Mustang.

Realistically, anything over 500 on the street can be sketchy. I got tired running in race mode all the time on meth injection and slicks, so I pulled the springs out of the gate, sold off the meth kit, bought vp 116, drag radials, so it's just an 11.0 sec car at 120 on pump 93 unless I want to go to the track.
