1970 LT1 shock numbers F40 vs F41 front and rears

[Grant W.]

Not up to speed on 1970 LT1 stuff
I need to know the part numbers for:
1. Original stamped numbers on standard F40 front and rear shocks
2. Original stamped numbers on Heavy duty F41 front and rear shocks

I have a set of 3192197 fronts and I think these are standard F40 shocks

Any help is appreciated. Now I am collecting parts for a 70 LT1
Any one have a source for the 884 alt, 0010 intake, heads, carb 3972121, LT1 hood, starter, 608 water pump, 709 fuel pump
Valve covers, Engine assembled May 27 1970
Actually any leads would be great.
Thanks, grant

Re: 1970 LT1 shock numbers F40 vs F41 front and rears

3192197 doesn't come up as a good GM part number in my sources.
The GM Corvette parts book shows the following part numbers:
3196957 Front, 1963-1980 with H.D. suspension.
4940459 Rear, 1963-1977 with H.D. suspension.
4975486 Front, 1963-1977 except H.D. suspension.
4975487 Rear, 1963-1977 except special performance suspension.
F40 and F41 are not referenced in the part number descriptions.
However, in the "GM Production Options" descriptions, the following are given:
F40 = Suspension - Heavy Duty Front & Rear
F41 = Suspension - Special Performance Frt. & Rr.

Grant,
Nice to see you have seen the light and got away from those "Rat" motor cars.
I am not aware that 1970 had an F41 suspension option. Maybe in ZR-1's but not in all others.
My 70 LT-1 has #192196 front shocks but for some reason I did not record the rear numbers. Will do so in the spring.
If you need any photos along the way just let me know.

The 192196 jibes with the AIM too.

The P&A catalog part numbers are the on-box part numbers and are usually not the same as the on-shock part numbers.

F-41 was not an RPO for 1970. However, it was supplied as part of the ZR-1 package.

1970 LT-1 heads are fairly easy to find. Even if you find the 1.94/1.50 version of the 3927186 castings, these can be re-worked to 2.02/1.60. Bill Mock probably has the waterpump. The 709 fuel pump shouldn't be too hard to find on eBay or elsewhere.

Joe,
Thanks for the clarification.

Re: 1970 LT1 shock numbers F40 vs F41 front and rears

I would have the correct 3782608 water pump with casting date of D270(April 27,1970)for your 1970 LT-1 Corvette with engine assembly date of May 27, 1970. Pictured is an original "Survivor" water pump removed from the engine when new and a completely rebuilt one(this original water pump was also removed from the engine when new).
