In the middle of building the ole LT1.

Are these the correct rod and main bolts I need? Suggest another place I should purchase them from? Thanks!

Mains- http://www.texas-speed.com/p-2550-ar...e-journal.aspx

Ok thanks!


Not sure what this means lol

Instead of a bolt it’s a stud, it helps get the proper torque on the main caps and hold them in place. Idk what you are doing with the car but might want to look into it.

Its at the machine shop, its getting bored over to a 355, .030 over.

I am using stock rods and new rings and pistons. Also stock crank.

Using LE's 226/232 cam.

I can only get studs for the mains correct?

That’s kinda the way I went with my motor but I have LE1 and the 236/244 cam. Yes to my knowledge only mains. Also if you line bore the crank you might want to get a oversized crank timing gear, we are having one hell of a time trying to get the slop out of the timing chain.

Yeah I noticed your sig just after I posted.

So I am safe to get the rod bolts? Sorry, I just really don't want to order $100 worth of bolts to have them be wrong lol

I have heard about getting a bigger timing gear. hmmm ill check it out. I am still waiting on my block to get done.

Thanks for your help!

What do you plan on doing with the car? Reusing stock rods and then using main studs doesn't make sense to me. I wouldn't get into using studs until you really start putting some serious power through the motor, which then you might want to look into swapping rods.

It's just going to be a weekend driver / track car.

Block will pretty much be a stock rebuild. Already dropped the cam off. He is super busy right now. I told him in the meantime I would pick up new bolts for the rods and mains.
Would the bolts I posted in first post be sufficient? Will they be better than the stockers?

Yes, ARP 8740 chromoly would be stronger than stock by a great deal.

The rod bolts are the right ones I just doubled checked my box. I feel you I have had parts problems of my own from Summit sending me the wrong parts or the parts being missed boxed

i spun some bearings in my original engine thought that the $40 extra was well worth it

Have you heard of the white pressure relief spring for your oil pump? I heard its the best $5 you can spend for these motors.

How many miles, how much rpm, how much power? The increased clamping pressure would be warranted with more power/ rpm, but if you're going to be spinning it that high and pushing ever more power, why not upgrade the rods as they are the most stressed part of the motor?

Don't quote me but I have heard the stock rods can actually hold some substantial power, that it is the bolts that get weak first. Reason being why I kept mine stock, I'm a broke college kid on a budget.

I've heard of people using them, but I have never swapped springs into a stock pump. I've always swapped out my oil pumps for aftermarket ones.

I don't doubt it, they are powdered metal rods, plenty of people have gone plenty fast on a stock bottom end. I just think with what you have planned, ARP main bolts would be plenty strong.

this was on a 14x,xxx mile motor with boltons @ 6000rpm first time ever at the track. My engine builder said I would be fine because I’m not going to spray it. Im also in the broke *** college kid category, my dad is loaning me the money for my build, he wanted a completely stock build so I have to be grateful for what I got.

I put one in my new pump, Its super easy to install just take out the 4 bolts on the pump and you punch out the pin that holds the spring in then reassemble.
