5.2/5.9 H.P build guesstimate

Oh yes everything will be measured as always no guessing game, I’m just stuck between two cam choices right now,

222/228 @ 50 277/283 .494/.515

And the 230/236@50 282/290 .515/515

I was thinking if I port the heads a bit, add a windage tray, and up my compression to true 9:5
The smaller camshaft might work for me especially if I plan to drive this thing to work sometimes lol.

The crate engine peaks at 5400 because of the stock cylinder heads. If you put them out the larger volume will increase the RPM ceiling.

I do believe the small cam will be much more enjoyable for the street. Depending on how well the head supported, I don’t really see an issue with peeking at 6000 good set of ported heads

Cams are giving a general RPM range. Guys that are experiencing this tend to laugh out loud and call this bullshit at a lie. Partly because it is because one camshaft is labeled for all small blocks covering the same RPM range. Impossible 273 in a 360 and have the same RPM range.

Charge the top from the air cleaner through the carburetor through the intake manifold and the cylinder will allow the cams to be extended a few RPM.

Likewise, just the reverse. If you installed a restricted air cleaner, too small of carburetor a restrictive dual plane and small port I wouldn’t be surprised to power happens at 5000.

The smaller cam may not pull that vacuum either, depending on where the LSA is ground.

Bingo
