Looking to burn my tax refund on the GXP. I was looking at MSD coils. I was wondering if anyone had used these before on any LS engine? I am skeptical of the benefit given the $720 price tag. I was thinking of this or having my torque converter redone for a higher stall speed.

I am not sure if these is the exact application. I have to call them. The pricing is very close for all 3 LS engine coil kits.

Appreciate your thoughts.

The factory ones are pretty good. I would say to put your money somewhere else.

No....total waste. Put that money into cam/heads/converter...

The factory ones are great. they will hold up to turbo/nitrious use. Buy something else.

stock coils are fine. put your money into a tranny...

i saw a ls4 block with 0 miles on ebay for 400. would be nice to bore and releeve that baby out to 4+ inches. dont think i want to put 10k into a new engine/tranny setup atm tho. http://cgi.ebay.com/ebaymotors/ws/eB...m=260346522932

I wanna bore and stoke an LS4 out to a pontiac 421 or 428. That big of a motor though would make tires hide from your car. not to mention the tranny

plus i would want to tap/plug all those dod oil holes and the oil sender hole and relocate that to the side of the block.

I'd say rockers or a trans. if you plan to keep the car.

The factory coils have proven themselves over 1000HP. I'd put the money in some bolt on parts or some JUICE

Save your money. There is not much out there for these cars.

You are better off getting a project car and going from there.

could get a f-body for like 5-7k. pretty sad that my truck was that much.
