bad news on my 99gtp

once i build it im not planning on taking it back apart but at the same time in not build a ground pounding rocket just want i reliable toy i can pound on from time to time
 


just scrap what i have? so basicly i can get a junk yard engine tear everything down but the mains and do what i want from there.
 
just dont touch the bottom end, stop after the heads are removed. Leave the crank, pistons, rods and everything that keeps them in alone dont even look at them
 
well can i change the oil pan gasket mine leaks now and my na monte leaked too so did the one i tore down and apparently ruined
 


i think ill just keep what i have in the car now then and port my extra heads cam it and put my rebuilt sc on it car has 132k on it good for a 97. it may already be camd idk thanks for the pointers i appreciate it
 
I've always been told if you shift the mains around, it'd create a 500~ mile wonder without having everything machined and aligned.

Maybe so, maybe not.

Regardless, just get a junkyard block and toss it in.
 
when you say to get a block you mean an engine right? ive mostly delt with small and big block chevys so to me a block is a bare block
 
if you can only find a n/a motor your only using its block. you need supercharged heads. if you find a good sc engine leave the heads on unless you plan on porting them or some thing.

you can always do a compression test in the junk yard engine before you buy it, and most yards give you a warranty. yes your doing the job again but the engine will be replaced for free. part of the gamble.
 


Update on my car. I just pulled motor out today and pulled oil pan, checked the #6 rod that I took loose when checking motor. The bearings were fine. Started removing 1 by 1 and found #1 rod bearing to be the cause. I have ordered a used engine with 156k miles that I'm gonna put in and drive. While building my original engine. Gonna put diamond pistons,h beam rods, ARP bolts in the entire engine. Intense stage 3 cam and heads, smaller pulley intercooler, and new trans to hold power. Will be about 2 years in the making but I want 450-500 whp
 
and 3k in machine work.

Be alot easier to tear the "new" motor comming in, rip it to a short block and build it up from there, 70% cheaper to

gonna have to give up on the M90 if you want that kind of power.
 


So its not really beneficial to build the bottom end? I would like to make it bullet proof so this don't happen again
