Stocker info needed
 
I have a 68 chevelle wagon with a BB in it (not stocker legal) and im thinking about turning the car into a stocker. How do I find out what drive train combo I can run? I tried looking it up on NHRA.com but my head was spinning. Im curious as to what class letter I can run and options, weight, ect. Not looking for saftey of modification fules as those are easy to figure out, just looking for possiable combos. Thanks in advance.

Depends on how much you want to spend. I'm pretty sure the first thing is you need to find out what the factory shipping weight of the car is. Once that is clarified you can find out what the car naturally falls in. I would say a good B/C SA class. Combos can be the sky as the limit.

Just noticed the "wagon" part. I would say its going to fall a little higher than the B/C SA class.

If I were doing a 68 Chevelle wagon, I'd be doing one of 2 excellent 327 combos, 250 horse rated at 245(natural M or N depending on trim) or 275 horse rated at 265(natural K or L).

You probably should take a look at the classified section, there is a 69 wagon for sale for $6200. You probably would have a hard time getting yours converted to stocker trim for that price.

Go to this page, the NHRA Stock Car Classification Guide, then click on 1968 Chevrolet:

http://www.nhraracer.com/content/gen...635&zoneid=132

That will list all legal combinations for 1968 Chevrolets for Stock Eliminator.

WHen you see this
327
*
250hp

12.88

One * is the Stock Eliminator rating; two ** is for Super Stock. 12.88 is the weight break for the car, which would be J/S with a four speed, and J/SA with a Powerglide/automatic.. A car can move up (I) or down (K) one class, with weight changes. Top weight break (12.00 for I, 12.50 for J and 13.00 for K) x the NHRA Rating of the engine (that 250 hp version 327 I listed is NHRA rated at 245 that you see when you scroll to the bottom of that column) + 170 (driver weight; all cars use 170) = minimum eight, with driver, across the scales at the conclusion of the run. So for J, 12.50 x 245 + 170 = 3,232.5 pounds for J/S-J/SA. You figure the weight the same way for I and K, using that Class' weight break.

For engine specs, camshaft, compression, valves, etc etc, refer to the NHRA Blueprint Guide, at http://www.nhraracer.com/content/gen...634&zoneid=132

It's a station wagon he is working with...his factor will be in the 13 - 15 range.

That's a good price if it will run under the index.

Might put a strain on a trailer tho.

Would be around 3700lbs at it's heaviest.

OK, its a "nomad custom" I'm coming up with
327 250 HP is 14.47
327 275 HP is 13.49

3787.50 for 250 HP
3709.75 for 275 HP

Does this look correct?

Yes, the 'factors' are correct.

327/250 fits at the bottom of M/SA, so you can run L and N also. Minimum weight is 13.50 (L), 14.00 (M) aand 14.50 (N) x 245 (the NHRA Rating on the motor) plus 170 (for driver weight) = min wt, across scales, with driver.
L/S-L/SA = 3,477.5 minimum weight
M/S-M/SA = 3,600 min wt
N/S-N/SA = 3,722.5 min wt

327/275 has been derated to 265 in Stock. Same rules apply. 13.49 is the very bottom of K/SA, you can run J and L also. SO you would use weight break (12.5 for J, 13.00 for K, 13.50 for L) x 265 + 170 = minimum weight at conclusion of run with driver.

I was looking at Malibu station wagon, but I'm not up on the wagon nuances. If it is what you say here is the way it would shape up -

327/245 - 14.29 @ natural M is 3501lbs + 170lbs driver weight = 3671lbs. Minimum weight @ M would be 3430 + 170 = 3600.

327/265 - 13.32 @ natural K is 3530lbs + 170lbs driver weight = 3700lbs. Minimum weight @ K would be 3445 + 170 = 3615.

I found it under chevelle.......it is badged chevelle nomad custom. They are origional emblems because my father has owned the car ever since I could remember (I was born in 73). Thats how I found the numbers I posted earlier.

I found a compression, carb, cylinder head, intake, bore, stroke, rod length. Is that it? No cam rule or do they just figure you can only fit so much in that package. Does it have to be a powerglide or can it be a 3 speed?

OEM lift which is 390/410 for the 327's, any duration. Look at the blueprint spec's for 1968 and it will show all carbs, heads, intakes, ect. for those combos...some parts may be superseded and aftermarket allowed. Any transmission with a maximum of three forward speeds allowed, same manufacturer as car. Between the rulebook, blueprint guides and aftermarket approved products you should be able to get a good grasp of what is needed. Plenty of folks here will be glad to answer questions as they come up I'm sure.

I want to try my 96 Cougar at the Orlando D2 race.
