I appreciate the heads up, I'm not the best option for stock parts, but I'll give it a shot.
I can't get the stock cam for that price. Could get you an LS9 cam for around $280. Or a mild Howards cam for ~$380, pick up some ponies.
I can get you those for that price, I can't beat it.
For mild springs I usually get the GMPP ones that are good for a little more lift than the BTR, those are $100.
I don't sell ZZP, cheapest 7.400 pushrods I sell are Cam Motion or BTR for ~$120
I can piece that together with the GM cover and hardware, etc.
Cost would be similar with the GM chain damper, could of saved some coin if the Cloyes chain damper was in stock.
Everything I mentioned is in stock.
