Default 63 Biscayne engine transmission recommendation
I have a 63 Biscayne that I'm going to be converting from a 454 to an LS series in the future. Looking for engine and transmission recommendations. My goal is around 400 HP with an automatic transmission.

Trying to keep this as inexpensive as possible so, that pretty much rules out a new crate engine.

LQ4 with a 4L60E is a good start. Just an FYI, 4L60E is a tight fit in that X-Frame, I ended up going with an aftermarket cross member in our swap.

I forgot to add that I'm putting it on a Schwartz performance frame.

Will the 4L60E hold up to the horsepower? I've already got one that someone gave me so, should save a few bucks.

Do a 5.3L with a cam or even a cammed 6.0. Just put a 4L60E in there as it will have no problem with that power.

lq4, 243/799 heads, and a mid sized cam should get you there pretty easy.
