Which engine, can't decide?

[Supspt454]

UPDATE:

Well, here is what has happened since the last post. Sold my GEN V 454, traded the TBI 350, and 4L60E for Edelbrock Conversion Headers for the LS1. SOOOOOOOO, it looks like I am going ahead with the LS1 conversion. Keep in mind, this engine came out of a 98 Camaro SS, so it has very good power as is. Here are the plans that I have to go forward with now, because this is all I have now...

I am bolting my Muncie 21 to this LSx. I am going to use a hyd throw out bearing, and keep the trans old school. The only thing I am kicking around now is...Keep it fuel injected, or go with the Edelbrock Performer RPM Carb swap and give it that old school look there... We will see!!!!!!!!!!!
