71 Blazer 4x4 stock 350 , T350 , NP205 want to swap in Vortec 7400 (454) Questions...
Ok i have a 71 Blazer 4x4 stock 350 , T350 , NP205 want to swap in Vortec 7400 (454), Asc far as i know and what i have read the 454 will bolt to the T350 fine .. ? right ? haha thats my only concern at the moment because i believe the mounts and everything should be about the same since Vortec or not its just a revised 454. And i know that the suburbans came with a 454 and i believe had a T350 behind them, I may upgrade the trans later but i just want to know if i will have any Bolt up issues taking out the stock 5.7 350 and replacing it with the 454. Thank you for your time in advance

Your 454 will bolt the th350 just fine. I would look into a diy4x motor mount and tell him your running a big block. Kert will hook you up with a motor mount that will raise the motor a little to clear that crossmember. Your also probably looking a little firewall hacking. The blazer doesn't have room for the big block so your going to need to make room! a body lift helps.
Hope that helps.
