Nice, I take it your not running yet? What rockers are a good option? I'm having a hard time finding a set of stockers for a reasonable price. I've been considering a set of roller rockers but am unclear on what ones are good. I've read that some of them are prone to failure...

My Mast small bore LS3's are getting T&D's, but I'm going solid roller.

I'd think stock rockers with a BTR trunion upgrade would be perfect for you. It's stock guides on yours, right?

Bore to 4.060" and go with small bore LS7s... they'll walk anything else you can put on the engine.

Ya they're stock guides, I found a set of stock rockers on eBay for $170 after shipping, plus the trunnion upgrade. That puts me within about $150 of some roller rockers. Would they be worth it or just stay stock?

Well, with rollers there's added weight and they ARE prone to introducing valve float... I'd talk to who's doing your cam and see what they say.

Mine isn't.

TEA TFS 225cc Cathedrals on a 416 and a Martin/Tick custom grind cam only makes 475whp/454wtq on a DJ.

Joke is on me...Stock inch LS3's w/stock heads make these numbers cam only.

something is wrong somewhere. What's your compression etc? Look up member LS2bait real name Tommy. His SS 6 speed car put down 520 plus at the tire using the same exact heads you have on top of a 416ci from SDPC. The car also was featured in GMHTP.....

Sure, plenty of people have made great power with them...that's why I didn't even think twice when I bought mine.

There has been countles hours, several dyno sessions, and part swapping dollars allocated to find a problem in my build. At this point I feel pretty confident saying there isn't one. Several knowledgable folks have independently looked at, worked on, drove, or tuned my car...no body has taken issue with the build or questioned whether it's running right, or not. It just won't make anymore power.

Only thing left to do for me is start taking parts off (heads, cam, intake) and try new ones.


I think I could mill a set of LS3 heads, throw them on and be ahead of my $2700 TEA heads

No joke and put some money back in your pocket when you sold them.

You have very nice taste in heads

Next piece of the puzzle is lifters... I was planning on using ls7 lifters till I read about lifters for 2 hours, now all I know is that I don't want ls7 lifters screwing my new engine up. What's my best option without breaking the bank? I'd like to stay under $500.

Also I plan on using stock rockers, I read that a lot of lifters require adjustment or preload, how would one go about this with a stock rocker setup? Is that just in the pushrod length?

dr_whigham

Morel 5315's are a big step up in quality, are around 200 bucks, and you still use the LS2 lifter trays. Check our sponsors. Some sell them cheaper.

As for preload, it's determined by the pushrod length. Is that what you meant?

Assman

iTrader: (2)

Ya that's what I was wondering, I'm not savy in the ways of adjusting rockers and wasn't sure if I'd have to get a set of adjustable rockers. The 5315 morel lifters sounded good from the get go but I just wanted to verify with some more seasoned LS gurus. Thank you!

I run the stock replacement lifters or "ls7" lifters. No issues here but I was on a super tight budget. If I ever build a stroker it'll have some morels or Johnson lifters. You won't need adjustable rockers but you will at a minimum need to know the plunger depth and the recommended preload as well as if any material was shaved off the block or the heads to get the correct length pushrods. Measuring is the best way, you can get a pushrod length checker(basically an adjustable pushrod) fom just about anyone who sells pushrods and lifters.

Tuskyz28

Just can't go wrong with morel lifters. Sure they cost more but they operate quieter than those LS7 lifters. I hate a motor that ticks a lot due to cheap lifters...... it's annoying

dr_whigham

iTrader: (49)

Couple that with the fact that LS7's were made for STOCK cams, low spring pressures... Even when they first came out, the LS7 has titanium valves...

I ran them on my Camaro. Knowing what I know NOW, I'd never run an "LS7" lifter again. Things do work. No doubt. Plenty of people have ran them w/o issue, myself included. Doesn't mean I'd ever do it again.

The summit ls3 heads keep getting pushed back, now they're supposed to ship in mid May... I can't wait that long, what's the next best cost effective ls3 head? PRC?

Oh and I got my motor, I'm stoked to get this thing going, the heads are going to be my holdup. The stroker crank has a keyway and my stock balancer does not, what after market balancer is best without breaking the bank?

Here comes the little things that start adding up. ATI makes a real nice piece but $$$, I have used SLP, Powerbond ( who I think makes it for slp ) would be fine, If your using the f-body accessories then make sure you get that one, don't be like me and not read the sales and or what it fits. If your using the corvette accessories I will make you a smoking deal on a new balancer in have, lol
