What lengths of heater hose?
For my 75 coupe with a new ZZ6 turnkey. I got new 90 degree Edelbrock fittings for the heater hose connections at the water pump and intake manifold.
What length of each hose (5/8" and 3/4") do I get? Don't want any splice jobs lol.

If your car doesn't have A/C just get 6 foot of each size, you'll probably use 4+' of one and 4 1/2' of the other, maybe more depending on how you route them. If A/C get OEM hose and trim to fit. T
For the 69 with A/C the hoses were purchased from Dr. Rebuild. They were preformed and were a perfect fit.

These are the hoses I used on my 77 A/C car following factor path. Trimmed ends at 90* so they tuck up nicely at the core, and cut to length at pump and intake.

Since the hoses make a 90* turn, to enter the heater core, basically underneath the car, going with hoses that already have a molded-in bend, is definitely the way to go. I tried to do the job with bulk straight hose, once, and only once. Didn't turn out too well, and I had to re-do it, with the pre-bent hose.......

hmmmm. Every thread I read said specifically the 5/8” hose goes to the intake manifold and the 3/4” goes to the water pump. Such as this one:
