I'm getting ready to spend quite a bit on my LT4 for modifications (Cam, Heads, exhaust, etc.) and stumbled across DRM's LT4 "Top end Kit" on their website. The kit consists of:
350 cubic inches - Ported cylinder heads - High flow stainless valves - Performance valve springs - Titanium spring retainers - Chrome moly pushrods - 1.6 intake and 1.5 exhaust - roller rocker arms - DRM hydraulic roller camshaft - High performance timing set - 52mm throttle body - K&N air filter - Modified air filter lid - High volume fuel pump - Adjustable fuel pressure regulator - Stainless exhaust manifolds - and Custom computer calibration.
DRM rates the kit at 410 HP/375 ft-lbs. torque. That of course is only 80hp more than my stock LT4 produces. The kit costs $6000!!! That's $75/per HP. Ive heard the stage II heads/cam kit Chris sells at Speed Demon will produce WAY more than that, and the cost is less than HALF of DRM's!
Is there something I'm missing here? Just curious before I make such a big investment. If not, I'll be giving you a call soon Chris.

Re: Doug Rippie "TOP END KIT" (scorp508)
His name is worht it. All his work is quality. Chris Lester just had a 368 done on his 94 ZR-1. Everything works flawlessly and has had no problems. Rippie delivers what is advertised. While your car is there, toss a little more money and get some suspension and radiator work done too.
As far as the video, that would have to be more driver related if both cars are putting down the same HP.
80HP more than your stock LT4?. Guess you forgot the LT4's push a little more than the advertised 330HP. TRy like 350-360HP on average. That 410HP is only 50HP more. That's alot of $$$ for only 50HP. :crazy: :yesnod:
DRM does exactly what most Vette vendors will do... Multiply what a reasonable price would be by two times!! I do not disagree that they do good work. But good work can be done for much less! I put together my own "top end" package and everything else for much much less. I turned every nut and bolt myself and have put many thousand miles on the car without any problems whatsoever. I'm a firm believer that if they can do it... I can do it! It might take a little longer because I don't do it everyday, but the self satisfaction and pride is worth the dollar savings alone. Sure I cussed and busted a couple knuckles, but I saved a ton of money! My advice? Stay with a reputable local shop if you can't do it yourself. Do the parts shopping yourself from Summit, AFR and other non typical Vette vendors and you can save a ton of dough!

Re: Doug Rippie "TOP END KIT" (EricVonHa)
Mr joe blow garage probably only offers a warranty on labor. Rippie offers a warranty on parts and labor. That's where the tuner guys come into play. DRM, LPE, and Callaway all offer warranties on their work.
Just checked Lingenfelter's site: 415 BHP / 385 lbs-ft of torque
$9,100.00!!!
That's $3000 more than the DRM's! With the SAME horsepower rating!! :confused:
Gimme a break! No question that they do great work(for that price they ought to do more than that ;) ). Definately shop around for parts and labor- I think you can beat that by a few thousand dollars. Try More Performance out of Charlotte(WWW.Moreperformance.inc). Also, you can get a lot of free info right here on the forum. I have less than half of the $$$ that DRM wants for his top end package and he is no where close to my numbers. As stated earlier, you do get a warranty for your money- no matter what it costs. Good luck.
Well, you know where my vote goes!!! :) :) We offer the BEST heads on the market right now. I am very confident of that! :)
Give us a little while longer and you will be reading about us and seeing us on the cover of magazines!!! ;)
Let me know if I can give you any more information.

Re: Doug Rippie "TOP END KIT" (2FST4U)
The DRM motor will put out more than 410. You are getting a warranty that they do stand behind. Some turners don't like to claim the max. I think everyone apples to apples is about the same give or take a few hundred. Sure you can do it yourself cheaper and it's fun but not everyone will feel confident turning the key to start it the first time. Make sure every thing is the same.

Actually, you cannot compare apples to apples, because there are things that we do that I am pretty confident DRM does not do nor anyone else with out heads! As close as possible though(even using DRM headers in my package) I am still quite a bit cheaper. :)
Ported cylinder heads...................2000
Chrome moly pushrods....................80
8 1.5 roller rocker arms..................125 (This is unnecessary with right cam)
DRM hydraulic roller camshaft.........275
High performance timing set...........200 (depends on set)
52mm throttle body......................300*
K&N air filter.................................. .50
Modified air filter lid.........................20
High volume fuel pump..................135
Adjustable fuel pressure regulator..100*
Stainless exhaust manifolds...........400*
Custom computer calibration..........350
Total for parts.............................4035
* IMHO this stuff is a waste of money.
Jim Pace GM performance (www.paceparts.com) states that the LT1 to LT4 conversion kit bumps the LT1 to 425 hp for 2100. If you have an LT4, you only need the LT4 camshaft to get to 425 hp plus tuning. Figure 175 + 350 = 525. So why bother will all the other stuff and the extra expense and work of installing it ?

Those guys chased each other all day...even when I was in the Yellow Z06, we were chasing the TPiS car, and it just came down to how hard was the driver willing to push the car through the corners (and believe me, they really pushed them through the corners!!!!).
Very true...HP was about the same and they all topped out at roughly the same speed.
I had my Corsa's put on at DRM...and they were a great bunch of guys...and believe me, part of the price is all the extra time they take to make sure it's perfect before it rolls out of the shop...
Mike put on my exhaust, and probably spent 1 hour just lining everything up to make sure the spacing and how much the tips stuck out was perfectly even...even making sure the pipes were clamped in the same spots.
He just replied..."Vette owners are picky and we understand that...so are we" :D
Lets see 4000 for parts 2000 for labor i think its worth the labor especially on youre precious vette knowin that a very well respected tuner as drm would be working on everything and making sure everything is stretable and reliable.
There close to me and i want that top end package to :) ...Im the type id hate to get the motor touched because of the low miles so i might do a torq converter and gears for half as much and get the same performance as the top end kit. If i did top end kit plus gears and converter id really be flying :)

Do you think they get the parts for $4000 ?? I don't think so. ;)
