Do you think we could order another set of headers using your pattern? Do you think they keep the pattern on file?

i suggested to them that they keep a pattern or whatever. might call stainless headers and ask them. if you are using the renegade hybrids engine hoop it is necessary to relocate the remote water pump mount. not a biggie. do a search for Stainless Headers...company name.

Probably a bit late now, but I tried calling them for a copy of your headers a couple months ago, and it was a no go. They didn't keep the jig.

These conversions are always interesting and fun to watch as they evolve. Don't forget that you will need to do something about your tachometer so it will read correctly with the LS7. The two extra cylinders will make it read 1.33x faster rpms than actual. Check out my post about the little adapter product I did for my own conversion and that I have been providing to other enthusiasts.

thanks bob. i do not use the vdo gauges but rather livorsi gauges that are supplied input from the mast motorsports ecu via a can system. dont know how it works but it makes for a neat system...especially the gps speedometer. thanks for the suggestion.

[lin7310948]

well i think that this project is finished. as you can imagine the combination of lighter rear engine with much greater hp and tq results in an overall better handling and driving car. i did not weigh the engines but i would estimate that the rear of the car is easily 100-150 pounds plus lighter. final comments ....you do not need 700 chp in a street car! it is way to easy to overpower the rear traction and cold tires on cold pavement can be a recipe for a serious mishap...so all you LS conversion guys...pick you spots and times carefully and stay safe! maxwedge528

Larry,

Not sure how I missed this whole build thread, but WOW man, the car looks great.

Your old engine is still waiting for me to get the car back together. I am getting closer every week. I am finally emptying out the bins and zip-lock bags and parts are starting to be assembled!!

Hope all is well

hey brendon, thanks for the compliment. ive been out of town this week so late responding. i have been following your work on your project and it seems that you are doing a really good job. hope all is well.

[lin7310948]

well i have about 4000 miles on the conversion and all seems well. i did have to have the alternator rebuilt...40 bucks and maybe thirty minutes to remove and replace. i have not measured gas mileage but it seems reasonable...maybe 20 miles to the gallon. cooling system is working well but still have hot weather coming. oil cooler location seems okay and oil temps at interstate speeds are 190-200 degrees. it will be interesting to see how well temps react to the coming really hot weather. i dont expect anything out of the norm but you never know until you know! i still dont like the look of the polished fm5 wheels but just have not worked up the "just do it" attitude to change to all black!

I have a twin turbo f.i. small block it will have close to the same h.p. as yours. I have a 78 930 tranny in it. Is it way overpowered? I loved your build, beautiful car. enjoy!!!!!!!!!!

[lin7310948]

took my other v8 conversion out for a little drive down the interstate today. it has an all aluminum dart 434 cubic inch sbc roller motor that makes almost 600 chp. it is a 71 rs conversion with all the stuff that most guys modify or install. it also is fairly light at 2300 pounds. i had forgotten how light and tight that it feels even though the 930 has more power and weighs about the same. acceleration in fourth gear happens very quickly...third gear synchros are shot!

[Packy]

what tranny are you running in the narrow body?

[lin7310948]

it has a short bell 930 transaxle with kennedy stage 2 clutch and pressure plate.

[Packy]

what trailing arms do you have? 930s? I'm wondering if the power tears up the bearings on the aluminum SC trailing arms.

[lin7310948]

i run late carrera trailing arms i believe with the carrrera axle and big bearing constant velocity joints. rear wheels are lindsey modified 9.5 by 17 with 275-40-17 kumhos. as you can imagine the 434 cubic inch motor develops over 600 ft/ibs torque.

Man, incredible cars, you have my highest respect!

[lin7310948]

thank you. they are not for everyones liking but they are still my porsche passion! and both are fun to drive!

Oh man, that sounds sweet!

[Rebel911]

Sounds good. you have to find someone with a GoPro and suction cup mounts
