My previous posts.
If you read or answered my 4.3 vs 283 or port vs direct injection posts. I would like to thank you for the opinions.
Last week I decided to put a mild LT1 I am building into my Nova when the time comes. The engine was supposed to be for my C10, but I do not wanna give up the power I have now. Rather I will just fuel inject it to clean up the issues I have been having with it. Namely weird drivibility issues due to the cam/carbs inability to play nice, and weak ignition. I was hoping for a more fuel efficient combo for the Nova, but it always dived deeper into chassis/body modifications then I am honestly willing to go. Along with a much higher buy in cost then what I already own. So any mpg savings would be eaten up by extra cost. Plus a bolt on LT1 in the 90's Camaro or Caprice will get more then enough mpg for me to just go the easy way. Plus with 375+hp it will be a awesome driver. Right now for the C10 I am deciding do I want the Holley terminator max with stealth tbi for the look. Or do I want the factory manifold with the LS computer for durability. Both with be fuel injection, and have LS coils. Using torq head cam/crank position sensors. So either way my engines tuning issues will be over. |

Giving up power vs a 307 to a lt1?
The lt1 350 will make more power everywhere. Grab a carb intake/carb intake /distributor and electric fuel pump and swap it. |

I have a 95 Z/28 convertible. The LT1 has gobs of power. Even with my 2.92 rear gears, I can roast the tires from a standing start. The Optispark is the weak link, but if you have a vented one and keep the moisture away from it, you'll be fine.

In my Nova gaining 125hp atleast. I haven't ruled out the carb/dizzy on this engine. As it will be a 9.6 maybe 9.7-1 LT1, gasket matched aluminum heads, and factory Corvette cam. So it would work perfectly with a dialed in quadrajet. |

I have a 383 LT1 long block that I will make into a better engine in a few years when I get some projects gone. |

Re: My previous posts.
Smart choice. I went super old school with my clone of a '70 LT-1 to take a break from electronics, but I'm a huge fan of fuel injection and have even designed (nerd alert!) three PFI systems for research experiment engines based on a DOS PC and handfuls of chips and prototype boards and solder and wire and software written in QuickBASIC.
You'll do great sticking with the '90s system.

Re: My previous posts.
If you already have the torque head timing cover I'd run the 411 PCM conversion and be done with it. If you were converting to a carb intake with a distributor hole I'd say go with the terminator x stealth and a dual sync. You could run the Holley with the torque head, but with what you'll want to do I think the factory LS PCM will be better suited for you.

All I need is a fuel pump, and some hose work. Get my fuel injectors rebuilt, and a base map installed on the pcm. I just really want the Holley tbi set up for the look. I love the look of carbs on classic engines, and want to keep it. Although either one should do the trick. The factory set up should prove to be more reliable over the years. Just not as good looking to me. Al though I could get a TPI from First TPI, and modify it to carry the rpm better. |
