Timing or adjust carb after exaust install?

[86suburbanNJ609]

Just got the exaust put on today. (Pics on here already)
Do I need to adjust timing or carb after the install I noticed she is a little hard to start after warm up and definitely running 10 degrees warmer. The shroud is not back in yet getting a e-fan this weekend. Everyone I talked to told me not to touch anything exaust shouldn't effect anything. If anyone knows what thread on here has the info on what e-fans fit in the shrouds on these truck would be appreciated I seen it on here awhile back I can't find it would help too.

Exhaust changes shouldn't have enticed a change in temps or starting that I know of. What's the timing set at? gmachinz posted before a 93-97 Ford T-Bird dual speed fan fitting nicely in the shroud.

No fan shroud? There's your 10 degrees warmer problem.

I know with fuel injected engines when you replace the exhaust you can lean out the engine and require a tune. I had this happen on my vette and the crotch rocket I had.

It depends on how restrictive the original setup was overall but if you were already running a modified intake and carb setup then probably not.
