Hey all, my friend has a Chevy 489 (bored and stroked 454) for sale and I couldn't pass up the opportunity to buy it. The motor will be swapped with my 350 and I have a few questions about the swap.

1. Would I need to do/buy anything else beside motor mounts?

2. I will mainly be driving my truck on the street and occasionally on the strip at local races. My rear end gear ratio is a 4.10 and I am wondering will higher "highway" revs hurt my bbc? I wouldn't think so, but I've had a few different opinions.

3. Will my TH350 be a reliable transmission? Will I need a shift kit or another torque converter?

Any and all help is greatly appreciated. Thanks in advance!
