I dont know how I feel about taking the stroker to 7k, but with appropriate valve control I don't mind trying

where are you guys ordering custom length pushrods from? I'll probably need a few different lengths when I set this thing up finally

My nephew shifts his 434 63 Nova ht I could swear he said @ 7800 and its just a 400 sbc stroker with big cam big heads. I think an LS is stouter bottom end so shouldn't you be ok at 7k? Miss my C5!

What I was referencing cost wise was the generic chromoly standard lengths that everyone sells around $100 range. I think My mantons where around $250

Gotcha. Well most people just generically throw 7.4’s in without measuring. Mean while most stock setups with 7.4’s already exceeded the preload suggested for stock by hitting .120-.130

His suggestion was a 236/240 .600/.600 114+4

seems like the duration split is small for square ports, but then again I don't really
know squat about cams

If the people doing cam swaps even buy pushrods... LOL

I found a good video for the cheapskates that don't like to buy the correct tool and take the measurement. I found it on this site when doing some lifter preload research. I came across this page. NOTE: I am NOT endorsing there products in any way, just sharing the tech article I read as I feel it has some valuable information. I have never done any buissnes with them. https://gwatneyperformance.com/lifte...ont-hurt-will/
