Opinions of this Slant 6 video

Yes, if I want to drive to car cruises, I cannot gear the rear end too low, or it will not be practical to drive on the highway. I think a 3:55 rear end may be a good choice for my use. Street performance is what I want to do with the car.
I ran 3.55 7 1/4 rear in ny 71 swinger. Built 225 w .460 /260* cam, full length header, 2400 stall. It was great till the middle of 2nd...then v8's would pull past ... that just sucked after all that work. 3.91 would be better.... but that would only fend them off a little bit longer.imo

You need 200 cfm int flow,.530 min lift cam , 9.5 static pump gas 8.2 dynamic ' to avoid detonation-chambers and plug location are poor, .3.91 min gear dual 2brl or single 500cfm carb, 2800-3000 stall quality convertor not cheap..IF you want to keep playing with v8 cars successfully on the street. The saving factor with all the LA motors... is the ability to swap to big port heads. The slant has a 'one size has to fit' head.
