Thanks for your info. That being said, will getting frame mounts and engine mounts then allow for a 4.3 to drop in on the 1984 S10 frame? There can't be much difference between an 84 and 88 frame. If there is I wouldn't know the difference and how much of a job it would be dropping in a 4.3. What bolt pattern does the 4.3 use? I am not 100% sure but I believe GM started using the 4.3 V6 for the S10/S10 Blazer in 1988. Correct me if I may be wrong. Thanks.
