The 505/511 kits are just more user friendly. Usually fit without grinding other than the little notch off the oil pickup boss.
And a TF 240 or 270 is still small for even a 505.
I do agree a big b-body is heavy and can use some cubic inches.
A 535 with TF 270s would be interesting though if someone else wants to try it. 😃
I don’t think you would go wrong with any of the kits for a mild combo.
