I've went ahead and broke down a previous post into more threads as a suggestion from a member...

Here's the lowdown:
I have a 95 Z28 LT1 A4 with less than 90k miles in good shape. I want to build my Camaro as a street car with 400rwhp. No drag time, just want to weekend drive it or so, not a daily driver. Just a simple build to be able to enjoy my drives and smoke some cars on the road if I have to. I am somewhat budget minded meaning I do have a budget and I must have a shop do it (I'm overseas right now). This is what I'm thinking:

ENGINE
-stock engine
-LE2 head/cam package
-1.6rr
-APR headbolts
anything else I need for the h/c setup that I'll need?
-58mm TB w/ported intake
-electric WP
-30 SVO injectors/fuel pump
-new opti/plugs/wires/coil
-pacesetter LTs/OR-y/pipe magnaflow catback

OTHER
-3.73 gears
-Dyno tune

 

So this is what I've got so far and I'm thinking it's pretty complete, but what are some things that I'm missing? There might be some suggestions about forging the block or just getting an LS1, but I would just like to know that, deciding on doing this setup, what are some things that I'm missing.

 

i really dont know what your asking, but i will start with a few things you left out of the H/C swap


rockers, pushrods, guidplates, rocker studs, dont foget gaskets.

 

Im with dangalla. If your going to build it might as well refresh the bottom end as well. New bearings, rings, recondition rods, crank checked, and etc. do it right.

 

..errr especially with 90,000 on the clock. Some people have pulled it off (but there's no telling how long) It's usually not accepted to internally mod the hell out of a high mileage engine.

better off starting fresh with a new shortblock and throw your money and time at that. That way when the 90k engine dies you'll have a 400hp+ monster to install as the replacement. 383 LT1 forged shortblocks can be had for cheap these days, I paid a little under 2k for mine.

 

I agree, freshen up the bottom end. I have 94K on my stock bottom end and also rounding up parts to do an LE2 build. I won't bother installing the stuff until the bottom end is put together.

 

yes, very good information. although you can get by with a stock shortblock you will be running increased rpm's and it is only a matter of time before it goes, if your going that far into the motor and your that serious about it at least a stock rebuild is in order

 

Plus, those miles are miles put on by the previous owner without knowing how the vehicle was driven or maintained. On top of that, I plan on a 200 shot as well so I already know the stock bottom end is not going to handle that for long.

 

the biggest killer of stock engines is high rpms. its hard to say because 90k miles, that motor could be beat to **** or good as new still- its a bit of a gamble.

if you wanna keep the stock bottom end youll probably be ok.. just try to keep the rpms down.

 

Whats the max rpm for a stock bottem end rebuild with ARP everything? Some guys are running 847 cam/heads and spraying 200 shot on a stock bottom end.
