71 Blazer 4x4 stock 350 , T350 , NP205 want to swap in Vortec 7400 (454) Questions...

[BlazerBoy]

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
