Boydness Posted December 19, 2011 Report Share Posted December 19, 2011 http://i1129.photobucket.com/albums/m509/Boydness/Corvette_001-1.jpg I am soliciting re-powering suggestions for my vette. I've missed the last several years of advancements, so I am open to considering any options. I will use the suggestions to start researching the option. Requirements: She should be respectable at the track and presentable on the street. Preferably, capable of driving herself to another state. I am willing to reshape the floor and firewall to accommodate. I was even thinking about a "Mighty Mouse" 305 setup, like the Malibu: http://www.jalopyjournal.com/forum/showthread.php?t=1494 I like the thought of a 20+ mpg vette. Maybe something utilizing MegaSquirt or otherwise non-carb. Throwing me some options and maybe a guesstimate on expense. I am thinking that I might use one of the set-ups for one of my wagons. Incidentally, if someone has a Ford 351M suggestion, I would especially like to hear it. I have a neighbor working to convince me that it is a great powerplant. :zoom: Quote Link to comment Share on other sites More sharing options...

2 Sweet Posted December 19, 2011 Report Share Posted December 19, 2011 Anyway, +1 to what Kirk said. LQ4 + T56 would be a good budget build Quote Link to comment Share on other sites More sharing options...

Boydness Posted December 19, 2011 Author Report Share Posted December 19, 2011 is this a trick question?? lsx + 6 speed = 25mpg and endless aftermarket opportunities A C3 LSx conversion is an option. I have seen a few of those. Quote Link to comment Share on other sites More sharing options...

Richard Cranium Posted December 19, 2011 Report Share Posted December 19, 2011 The obvious choice is an LSx with a T56. If not that at least stick with a GM drivetrain. Quote Link to comment Share on other sites More sharing options...
schmuckingham Posted December 19, 2011 Report Share Posted December 19, 2011 Which intake and carb combo? whatever carb is to your liking and Edelbrock makes a carb intake for those. Quote Link to comment Share on other sites More sharing options...
evil8 Posted December 19, 2011 Report Share Posted December 19, 2011 4G63 + Powerglide Quote Link to comment Share on other sites More sharing options...
Boydness Posted December 19, 2011 Author Report Share Posted December 19, 2011 4G63 + Powerglide Now that is a different option worth researching. What's that based on? Do you know of any builds? Quote Link to comment Share on other sites More sharing options...
Avenger1647545502 Posted December 20, 2011 Report Share Posted December 20, 2011 A decently worked-over Turbo 3.8 V6 would be a neat swap. Doesn't weigh a LOT less than a small-block, but there is a reduction there AND it does move the weight aft a fair bit. Given that most C3s tend to be nose-heavy and prone to understeering badly...

TurboNova Posted December 20, 2011 Report Share Posted December 20, 2011 I'm pretty sure that rear end is complete junk and anything much more than stock it does not like to hold the power. I'd change the rear and do an lsx swap or sell the car to me Quote Link to comment Share on other sites More sharing options...

I'd change the rear and do an lsx swap or sell the car to me Rear end seems to be just fine in his vette right now. Has a decently healthy 355 in it currently.

Green Bastard Posted December 20, 2011 Report Share Posted December 20, 2011 a 4g63 is a very interesting option, and like most cars it can be done, but it would probably cost a good ammount if someone hasn't already built a direct swap kit, personally I would stick with a gm drivetrain, I know a 4.3 could be decently built and still bolt to any tranny a small block can if saving weight (or shifting it back anyhow) is a goal, but I tend to agree with the lsx guys, very tough motors, just drop one in and spray your way to your goal.

OGRE Posted December 20, 2011 Report Share Posted December 20, 2011 Put a big cowl hood on it and put in a 4BT cummins. It can make as much power as your mightymouse 305 and get 35+ MPG. Quote Link to comment Share on other sites More sharing options...
FourString Posted December 20, 2011 Report Share Posted December 20, 2011 I actually admire this guy's creativity, or simple lack of knowledge of the LSx. To me, this would be a no-brainer in favor of the LSx and T56. However, there are some interesting ideas in here. I'm also curious about your neighbor's fascination with the 351M. This has been a problematic/anemic power plant for many people over the years. I'm sure they can be done properly with enough money, but then anything can in that respect.

I've considered the LSx C3 conversion, there are a few out there: http://forums.corvetteforum.com/c3-tech-performance/2226401-c3-lsx-conversion-directory.html I should have clarified, the 351M is more for the conversion of one of my wagons, than the vette. Although, I think that I would prefer the cummins over the 351M. Quote Link to comment Share on other sites More sharing options...
Cordell Posted December 20, 2011 Report Share Posted December 20, 2011 Buy any late model LS engine with computer and harness, all the swap stuff exists for this stuff. Pick any transmission from GM. Make as much power and have as much fun as your budget allows. Quote Link to comment Share on other sites More sharing options...
