Hello all,
This is my first engine swap that is not a direct fitment, & I'm starting to believe that I may be in over my head (as the title suggests). So, I'll try to keep this short:
I have had my '83 Grand Prix Brougham for quite some time now, it was actually my first car. The 3.8 bit the bullet years ago, so I parked it. I obtained a '69 Pontiac Bonneville & pulled the 428 & TH400 (all running) with the intention of swapping it into my GP. I currently have the 428/TH400 resting in the car. Now, there are obviously not many white ups that I have found detailing this swap, so I have done plenty of homework based on what I could find. I know I will have to mod my Driveshaft, I have found the Jegs crossmember I need, I have the engine mounts & have ordered the clamshells to mount. I'm not sure what to do about the exhaust & do not have the means to modify exhaust.
However, lately I have been considering selling the 428 & LS swapping it, but I'm lost at this point & could use some pointers. I want somewhere between 300 - 500 hp out of it, nothing crazy, she will not be spending much (if any) time on the track. I do intend to stick with a carb. What LS do you guys recommend? Do you recommend going the 428 or LS route? Should I keep the TH400 or sell it paired with the 428? Keep in mind, I'm working on a pretty limited budget.
I'm sorry if this post does not belong here, it just seemed to fit best & any help I can get would be appreciated!
