So it seems that though sbc's and LS swaps have been done, there has never been a "bolt in" solution. I am currently wondering if the mounts that have already been designed will work, or if i'll have to fabricate my own. I know once i have mounts for the SBC, i'll just need the bolt on mount adapters to go on the sides of the ls1. I was concerned about the length of the transmission affecting fitment of the motor into the engine bay but a bit of logic suggests that if the input shaft remains the same, then the overall length of the transmission is going to remain almost identical I don't have a measuring tape on me at the moment, but as the bare block on the 7m is around 23 inches long, i'm estimating with front accessories it's about 30 inches (inclucing the fan). Does anyone have the actual length (and width/ height) with the engine assembled?
te72, i'd love to get the LS6 as it's rated much better out of the box, but i think that for my goals an LS1 with cams and heads will be sufficient. My modified 350 is estimated at about 315hp (hasn't been run since the new intake and cam were put in) with a top end of about 5500 RPM.
By my estimation the combination of that motor at 5500rpm, with my 245/45/18's and a .753 final drive gear would top out at around 148mph with alot of balls along the way. That is of course if the chart i found is correct and my 87 Turbo has a 3.91 rear end (not sure as it was an auto-tragic to manual swap done before i bought it and i can't seem to find any consistent information about rear end ratios...) Any and all thoughts are welcome i want to gather as much of the correct information as i possibly can so i can set this project in motion and have a bolt in SBC Supra by Spring.
This also means i'll have a good 7MGTE for sale soon if anyone is interested.
