Just think its funny all the little **** things that make cars suck. Here are some tips from my rebuild. Yours may be different.

Got $250 ARP head studs and one of the nuts comes unthreaded. Dont realize it until you have the heads started.

Adding Double roller chain moves the oil pump pickup forward. Needed to modify pickup bracket, bend tube, and dent the oil pan tray where the oil level sensor goes in since it was hitting the raised up windage tray thanks to ARP.

Metal is aluminum..need to make steel brackets for dial indicators magnetic bases.

#8 piston should come notched for reluctor wheel clearance...look real close because they dont mark it in the box...tiny

Get a spiral lock removal tool

Cometic head gaskets arent marked at all. Make sure you dont cover the water passages.

SLP double roller needs the lower sprocket pressed on/off to advance/retard.

Experts recommend minimum 42# injectors for a 600hp NA LS1 but preferable 57#s so they are not anywhere near their limit. Can someone tune them? Not 30#SVO.

Front oil gallery plug is on national GM backorder...been waiting 2 weeks. $1.50

Still waiting for 90mm TB and March balancer...backorder

LSX intake for $800+ does not come with port gaskets

Dont clean gasket surfaces with silicon carbide disc.

97-98LS1 blocks shouldnt be bored to 3.905...oh well...

Ring gaps from diamond are 16/14 NA 18/16 small power adder.

$1200 Kooks Stainless headers dont come with gaskets and bolts

Z06 PCV upgrade isnt too bad.

Run your head studs again after they sit...they back off.

Push crank forward while torquing main studs

Make sure oil pan is forward.

Im sure i'll think of more...feel free to add.

I have the front oil galley plug in stock if you still need one. Just call and let me know.

thanks for all the info pretty helpful...now all i need is all the parts to build it

I will probably be adding to you list shortly.

SAM98WS6

By the way, these guys that build short and long blocks earn their money...trust me. I would buy from AP Engineering, Keith Kraft or More performance if I wasnt building this at home with my buddies.

ktmrider

Thanks for the tips....also sure I can add to the list shortly ( after Eagle regrinds their cranks ).

SAM98WS6

Oh yeah...notching the block because of coring shift...Callies rod bolt hit on 4" stroke.

get a service manual.

Using 20w50 dino oil to assemble...5W30 dino to start it up...switching to synthetic

bought an engine block heater for $30...warm oil when its chilly out.

The list continues, what cam are you going with?

If I can remember don't forget to remove all the coolant out of the head bolt holes or hydrostatic lock....cracked block!

Sam you sound a tad bitter

Thanks for tips. As for most shops, they most certainly earn their money but for the most part have already been through what you've been through, so they know exactly what to look for. Goes with any type of experience...

Shinobi'sZ

If the galley plugs are not in will you have low oil pressure or no oil pressure??? Where are they located at or under?
Thanks

good list, I've experienced about all of those issues too. This further illustrates that building an engine is alot more involved than slapping a few parts together. Those shops that sell complete engine packages know about all issues, and usually the cost of buying one complete is more than fair since you can avoid the headaches.

Sam that's a great list...thank you for sharing it.

I found out the Cometic don't have ANYTHING on them. I was assembling a SBF, I have built tons, but have always taken Fel-Pro's "FRONT" stamped into the gasket for granted. I called Keith Craft, whom I bought the gaskets from, ask them. "You can't just line the water holes up"..lol. OK, how many Fords have you guys built? Called a few friends and let instinct guide me....whew, guessed right!

Good to know about the timing chain...never would have guessed that.

SAM98WS6

Ok guys..here is last nights saga.

ARP is sending me a new nut...and free too...yeah

SLPs Timing set instructions suck...keyways to the left of standard are advance and keyways to the right are retard..dont use standard dot when using non-standard keyway...who the hell writes that ****? ever hear of clockwise or direction of crank rotation?

Cam was supposed to come in at 110 dot to dot...mine came in at 106 after doing it twenty times...242/250 .595/.595 109...Piston to valve was .165 exhaust closest.

Try degreeing a cam with new hydraulic lifters....you know what im talking about..

Dial indicator doesnt like staying on the damn comp 1.75 rocker...pushrod hole on top moves it all around...it was a bitch to set up.

There is not an easy way to turn over an LS1...just flywheel bolts in the crank sucks..what do you guys do.

Pretty sure you can use a standard 5/8" plug in the front of the block. Those ring gaps are for your bore size, and should not apply to every bore size and combination. File fitting rings sucks

SAM98WS6

Your right. Thats what diamond recommended for my bore size for a small power adder...say a 150 shot. File fitting rings hasnt been the worst part so far.
