Who's done the LT-4 conversion ?
I was wondering whether it was actually worth it or not. Are the "425 HP" statements accurate? I have the LT-4 heads with GMPP 1.6 RRs on my 94 TA now, but I didn't get to do anything with them before I put them on. Otherwise stock except for the built trans, what kind of gains should I get from them ?

The advertised HP is achievable as long as you have headers and tuning.
1.6 rockers and heads are nice, but you will also need a bigger cam to take full avantage of them. My guess is that you're around 300-315 RWHP right now, depending on what else you have.

How long does it take to do a cam swap, with shop use and air tools ? I've never done one, but I'm a mechanic. I coulda done the head swap in a day if I'd had the parts. Also, has anyone had an EGR problem after the head swap? When I hook up the vacuum line, it idles very rough.
