unless they were noisy, id say reuse the stock lifters. dont fix whats not broke. what size injectors were on the car? i would say it will be getting too much fuel when going to the m90. but only a scan will tell. take your time and scan scan scan. if you plan to mod the car, i would start with a good foundation. i would say go with the used shortblock. have the heads checked. maybe have em cleaned up a bit if they are not PnP already. depending on the cam thats in the car, go with a nice cam (if you are wanting to mod), go with a rollermaster timing set while it'll all be out infront of you. i would upgrade everything that is easier to do with the motor out of the car. imho. anyways good luck man

The lifters were fine as far as I know .. there were no odd noises or such.

The car is highly modded right now. It has 42# inj. The heads are P&P W/ bigger valves and have only 5K miles on them. XP cam already installed as well. TOGS, full 2.5 exhust all the way back NO CAT stage 2 IC and its going to have a 3.3 pulley on for openers. I just received my Ls1 scanner today now I need a running car to learn how to use it .. lol.

I understand upgrading everything while it is out of the car, but iam only relpacing what is absolutely necessary.

Thanks for the reply.

When I put the motor back together I bought all brand new gaskets. The car basically went 3 total miles and did some idling time. Do I need to replace the intake gaskets?

 

[burtgtp1973]

I should of added, these are the new stlye aluminum gaskets.

2. Is it Ok to re-use the connecting rod bolts?

it's possible but generally not a good idea.
