318>390 Stroker.......Your thoughts

He has a good point Bewy. It’s a PIA to get it working in the head and on the paper. I also have to say that I think the cam is big for the stroker set up. Not without domed pistons. IDK if that’s available for this combination. Also the cylinder head is small for the cubes. Beyond a regular street runner of 370 cubes, that Edelbrock head is limiting. Even at that it is depending on what your doing.

IF it were I doing this, the first step would be to seek a little more compression with this cam or use a smaller one. Port the heads out rod use of the 1.6 rocker, 1-3/4 headers and couple it with a 4.10 gear at a minimum. (3.91’s with the next smaller cam)

I’d also look to put the cam on a 106, not a 110. It’s IMO the 110 will leave the 390 a little soft on the bottom despite its CID.
The cam timing events are key to the power.

@Dave81, I think your combo will perform very much like the BluePrint 408 with the power band shift upwards 500+ RPM.
I suggest the 1-3/4 header (min.), 1.6 rockers and having the cylinder heads well ported. That should release a good 70+hp.

Thanks.
The heads may well get machined at a later date. I already have them and they are better than any stock head available in the UK. Cost is the killer here and I've already blown the budget due to exchange rate and parts cost hikes due to availability etc.
