Default Solid Lifters?

Anyone running Solid Lifter buckets in their LT-5....my machine shop though I was giving up some decent hp by running hyd lifters. I would think that we would not have the ramp issues as you would with a traditional OHV setup. Any thoughts?

Audi/Volks make a solid lifter that would work in the LT-5

How are you going to run solid lifters in the LT5.....How are you going to adjust clearance?

How are you going to check clearance? To install the solid lifters you have to remove the cams....
To adjust the solid lifters you have to remove the Cam Covers.....

I do not get it.....this is beyond me

When you are regrinding cams one has enough excitement making sure you are within the max and min lift of the hydraulic lifters
let alone using Solid Lifters

Over and Out

Would be the same way you do solid on other DOHC cars...Mercruiser actually did it so have others.

what hp are we giving up? My hydraulic buckets are good 8000 at least, and nearly as light as mechanical buckets. If the lift curve is designed for hydraulic you won't be giving up anything.

Too much hassle, no benefit imo.

I'm w Todd. Maybe Al or Pete may have investigated and have some additional insight.

LS motors can run up 30-40 more HP with a solid lifter motor on the same cam specs.....hyd is not always as consistent. When they were planning the LT-5 racing engine, including the silver state...those were all solid lifter cams.

I am guessing the Bonfiied LT-5 with 550hp out of a destroked 5.0 is runnning solid lifters also....I guess its hard to say what we are and or are not giving up if no one has tried them. Obviously the folks in the LT-5 program saw them as beneficial

Looking at old threads, looks like Flyin Ryan said that solids are better than hyd any day, but could/would be a PITA....5% increase in power. So another 30 hp

I'm really wondering if there isn't someplace else with a better ROI to find 5% more power. The question is "What environment is this motor supposed to live in?" Full race or are you picking up groceries? Everything has its compromises.
I think its important to first state your objective here.

Going to town for Cappuccino.......just got to watch out for deer on the road

The deer are why I have Wilwood Rotors and C5 Z06 brake upgrades

Oh....and getting JD parts when I need them fast

I was just talking with a company...Adjustment is usually every 40K miles. However....to cover their ***....they advise every 15K.

Obvisouly with cams, radio delete, AC delete, and not flappy muffler I am not worried about a quiet ride.
