M1 Sb intake. Best for small blocks?

I see rumbles on this thread I'll leave it to him this is not my area of experience, I would think you would want to open up your intake port to a 340 gasket match size if it was me.
Thank you and I agree.
Matched to what gasket? A 318 or 340/360?

yes you could go back and grind them to match a 340/360 gasket.

but spending $400 for a dual plane M1 seems a little silly in this situation.

there was a small port Edelbrock LD4B intake. Look for that used.

I agree and the Edelbrock LD4B is one of those “Other” intakes from Edelbrock that can be listed. I really like that one a lot. Weiand did a copy of it. (Action Plus)

$400 is ridiculous prices IMO. If you yourself NEED to have it, fine, you can do it a lot cheaper with a;

Factory iron
Edelbrock Performer or other Edelbrock
Weiand Action Plus

These intakes sell a lot cheaper and will perform just the same at tour build level.
