273/ 2 barrel camshaft options

Hi there thanks so much for taking the time to share! This is completely different from what I’m reading the groups interest in using the isky e4, but I am learning and willing to consider any option. I will do some further reading and discuss the Racer Brown cam options with the machine shop.

I was unaware of Hot Heads and the option in using 360 valve springs. (Those will direct fit replace my 273 springs?)

Thanks an again and I’ll be in touch as more progress develops.

I have an Isky E-4 cam in my 273, but it is a 4 barrel carb and a 4 speed. Hot heads are into early Hemis from the 50's. It just so happens MOPAR small blocks use the same solid lifters and timing sets as the early Hemis. Hot Heads sell quality parts at really good prices. I learned this from my experience with early Chrysler and Desoto Hemis. All small block springs can be used in a 273. 360 springs are a bit stiffer, so they work well without going to 340 springs that have a larger OD and have a much higher spring rate. The Racer Brown custom cam is much closer to the 273 2 barrel cam and is also acceptable for a 4 barrel setup if you decide to upgrade later. That is what Eekvonzipper did with his 273 Barracuda.
