Hello all,

My dream when I was younger was to have a DZ 302. Something to do with a high rpm, short stroke, solid lifter cam motor always intrigued me. I now have a 62 Nova with a 98 LS1 and t56. The motor is bone stock.

Has anyone out there built a short stroke LS1? Obviously valve train would need to be top of the line, custom cam, etc. What stock reciprocating assemblies would fit the LS1? Think 283 crank in a 327 block, but the modern version of the classic DZ 302.

Give me ideas, suggestions, and feasibility of this build.

Thanks

i believe from the 4.8 to the 6.2 the stroke is all the same just different bores but someone might make a de strocked crank for an ls1. How high to you want to turn it?

I remember reading about this concept 302 Camaro a few years back, but it doesn't tell exactly how they hit the 302 cube mark. It still lists a 6000 RPM redline. Not sure if you wanted to spin it higher or not.

Not that I think this is a good idea, but the 4.8L engines have a shorter stroke with a longer rod. Personally, I would rather blow the budget into getting more cubic inches rather than more RPM.

It's a neat idea and would def be cool, but I think you would be better off spending the time and $$ differently :/

Does anyone make solid roller lifter cams?

High rpm's doesn't necessarily equate to high power. To be honest with you, the only way that the dz302's were fast was with 4.88 gears and headers and even then they weren't all that fast.

I understand this But its more of the sound and characteristics of an old TransAm racer that I am after. Eventually I would like to road race it. I want a stout rotating assembly and top end. I would only be interested in around 400 hp. I want to be able to beat the **** out of it and only have to adjust valve lash. If I miss a shift at 7k I don't want to have to push it off the track.

Not so sure you necessarily need a short stroke / big bore to get high RPM's. I was reading recently on some of the rod bolt threads here that people here regularly bring their motors to 7400rpm. Personally I'd be happy with 7000 - 7200.
Another example is the BMW S54. It's a 3.2 liter with a 87mm bore and a 91mm stroke. It redlines at 7800rpm.

It's not the stroke that is the big issue, it's the piston speed (which is obviously changed by stroke). You need a piston that can handle going up and down that quickly without blowing out lol

agreed, i rev my 383 to 7000 all day long, it has the best valvetrain though morel link bar lifters, 700 lift springs hardend pr's... but it is also forged with wiseco pistons.

one friend of mine runs his 402 to 7200+ at the track with forged stuff

i think(though i may be wrong) the limiting factor will be the valvetrain, not piston speed unless you have a stroke >4 which is kinda out of the question

have you considered running a stock stroke solid roller 347, that would turn 8000?

There's an outfit on E-Bay selling some used HUGE solid rollers, most are 270°+ and 0.750+. They've been trying to sell these cams for a few months now...
