Coming Soon: Higher Ratio Rockers

[3400-95-Modified]

I can build the lifters myself, I just need the internals...

LIM has to come off soon its leaking on either valley

And when I ment anti pump down I meant ones that would be like off the shelf or something, not the LS 3400 combo's... but if thats the only option I'll probably go that route.

There is a set of 15 on ebay for 34 bux right now.

thats good news because I have a 1331 exhaust lobe

It was just mentioned before not sure why really. As long as you say they will work for my application I'll probably be going for a set of 1.65's MAYBE 1.7's if I'm crazy enough...

Time to get some LS1 or is it LT1 lifter internals...

Oh any high rev anti pump down lifters at the end of this performance parts tunnel??

well only if i assemble them myself...lol. You can use either the LT or LS lifters...springs are the same. I can build you a set, it would only cost the amount of the donor lifters plus $20 for my labor...haha that is if you have 3400 lifters you want to send to me so i can swap em...or you can just go buy some new or used lifters...new from the auto parts store would be any of the new SBC lifters for the LT engines, which are the same as any SBC chevy really...but just make sure they are the newer models like 96 and up...or any of the LS lifters...dont buy em from GM they are too expensive, i know i was looking at that.

and im with you on the 1.65...seem like a good little boost...i mite go 1.7 tho if i get a wild hair

Where is this piston to valve contact idea coming from? 1331 grind with 3.4 DOHC pistons had over .200" clearance.

Flippin sweet.... Too bad it may cost and arm and a leg tho...

Oh are these rockers FULL roller too?

Damn, 1.7's would put my cam to a 549/603 lift cam... HOLY HELL... 581/639 on 1.8's

the 1.65 may be a good idea, that gives some a minor jump if they dont want to go so high, 533/586 on mine for example.

not so much an arm and a leg, just about what you would pay for normal off shelf perf parts...and i liked the 1.65 as well, gain a little of seat dur and some lift...plus keeping it smaller for no piston to valve contact, just like in the old days with the old skool pontiacs...thats all they did, use the same cam go with bigger rockers...and yes full roller lightweight alum alloy MADE to fit

[geldartb]

id be down for a set of 1.65's as well. ive been wanting these forever.

kick ass news.

Yah, i will say a large thank you to the community for supporting everyone, and since i am here at SD i will do my damnest to make the highest quality parts for our cars. I am going to be one of the first to use the manley stuff on my engine, and i have a project as well that will use them also. I am working directly with the companies, so there is no middle man. The good news is all of this will be available very soon to anyone. We will offer these parts off our website and off our cataloge, and they will be stocking parts, no more one off crap. good parts at good pricing...scratch that awesome parts at great pricing. So now you wont have to pay so much to play anymore...I am working on alot of parts, but these are the first to come down the pipe. We at SD may also offer performance FWD transmissions using all the newest Raybestos parts, as well as being a raybestos dist possibly, and looking at getting a bunch of off shelf parts made. I will also have an update thread for parts that are already on the market that will fit the engines as well. Now is my chance to help out, and ill make sure it counts. I cannot let all the secrets out yet, but there are more amazing parts to come from SD...

About the cost of a cam is the general idea. Should have a real price soon, which is why I already posted. You can run over .600 lift without a problem on the comp 26986 springs. John wanted 1.65 for the slight bump as well so perhaps more of those should be made.

Full roller, like the LS1 rockers Scorpion makes.

so necessary....

[blackbombshell95]

This is Epic!

Makes me want to start another project!

I'm curious of how much ratio change would cause valve interferience... I'm not even sure what clearances I have right now.

Damn, 1.7's would put my cam to a 549/603 lift cam... HOLY HELL... 581/639 on 1.8's

And your valves possibly right into the top of the pistons. It's exciting news and suggestive of the start of long overdue recognition of the 60 degree V6 potential especially since they are rivaling V8 output as high as the mid 1990s on just over half the displacement.

Someone brought my attention to a tool that can be purchased to flycut your own piston valve reliefs which I've been looking at since I found some drop in forged LS1 pistons. For boost it would be more effective to install the largest exhaust valve that will fit.
