V10 viper / 727 combo help
 

Looking for suggestions on who could help out on getting parts to put a 727 behind a viper v10
Contacted ati with no luck they only make a adapter plate to bolt a gm trans on it
Car will be in gt so I can’t run a glide or 400
Any help would be greatly appreciated

Contact Kevin Helms, he’s built one or two of them.

I think first V10's were glide cars. Dave at Pro Trans

Found a 727 that will work that came in the trucks for a couple years before they went to the 518 that all my good parts will work in
On the classracerinfo site it only gives hp rating with a stick at 450 hp no auto listed for the 97 488 v10
So Would it be rated the same with auto ?

Re: V10 viper / 727 combo help
 

I do not recall any year Viper ever coming with Auto = Therefore NOT legal
for stock class if that what you were planning.

Car is a super stock gt fwd conversion

Re: V10 viper / 727 combo help
 

I'm intrigued. What FWD conversion chassis, with the lack of firewall relief for any Mopar RWD conversions, does a V10 fit in? Bellhousing adapter wise I though the V10 was the same bolt pattern as a small block but a little research it appears same as the Cummins instead.

Depends what year motor you are looking at. The 488 bolt pattern will fit a 727 Early Diesel T/Flite I have two cases for that combo. Also depends how you plan on starting it. The later DP with the 513 motor has an an adapter for a GM Glide or T350 and both have different starting methods. Calll me @ 985-804-6161. I have a Viper with a t/f here that is for sale, and I had another. And can probably help you. Jeff Teuton or email jefft@southlanddodge.com

Thanks guys Got the trans covered now after talking with Jeff that has already done this

Re: V10 viper / 727 combo help
 

I have some new 727 TF cases to fit the Viper also.

Re: V10 viper / 727 combo help
 

According to the 2018 NHRA Rulebook in the SS/GT Section 12B page 12 under ENGINE: The first sentence reads...

" V8 only; must be same make as body."

That means a V10 is not currently allowed to run in SS/GT. This is not a new rule as people wanting to run a V6 in SS/GT in the past have been told they cannot.

Re: V10 viper / 727 combo help
 

Travis, While you're here, when did the GT rule change from where your transmission had to match your engine in availability?

Re: V10 viper / 727 combo help
 

Engine/transmission rule is still the same.

Re: V10 viper / 727 combo help
 

Oh, okay. So if the guide doesn't say A (automatic) only, you can run a manual trans.?
No question?

Re: V10 viper / 727 combo help
 

Not always true. Over the years there have been cases where it has been brought to light that a certain combination was manual only or automatic only. If there is a question whether an engine/body did not use both manual and automatic transmissions, that needs to be presented to the NHRA Tech Dept in writing so the combination can be researched.

Re: V10 viper / 727 combo help
 

Interesting.
So, now I'm curious.
The 91-96 Caprice is okay with a stick with one V8, but not the other?
Maybe the Venezuelan taxi and police option?
I wonder what trans? T-5 @ 4200 lbs.?
Also wonder if anyone can find the GM part numbers for the clutch pedal and other assorted linkage parts?

Re: V10 viper / 727 combo help
 

Maybe I should repeat my previous post.

Re: V10 viper / 727 combo help
 

No need, Travis.
I just didn't know it was our job.
If you would, tell me who to contact so I can get on the payroll.
