Cams Away!

@Garrett Ellison ,thank you! Here is my thing.....

A 340, a big bore/short stroke engine will like to rev up and make terrific top end power and being a short stroke engine & as long as the valve train is controlled well, it will hang onto the top end charge very well. If I could find a 1/2 step smaller cam from the Howard’s line up in a solid roller, I would have chosen that one. A solid flat tappet cam would also do well here. But that is if you want to run that SFT vs a solid roller. But with that cam...

Getting stock heads to work with it may increase the dollar amount on the heads final cost. I don’t know for sure, I didn’t check, but the spring seat may need work with the Howard’s valve springs. Then there is always another spring dealer to look at like PAC, Isky, Crane etc... Since the cost is getting up in price for not just a rebuilt stock head but one with bowl porting, (IMO) why not make a little more of a stretch and push to spring for Edelbrock heads, re-equip the head with the proper springs if the OE Edelbrock springs don’t meet the need, add a RPM AG, 750 & 1-3/4 headers. Now the above cam can start taking advantage of the extra air flow the Edelbrock head can support which will add some nice extra top end pop.

With a good intake track like above, getting away with a cam slightly smaller than 230@050 & making 400 hp is entirely possible.
