With stock manifolds hot starts should not be a problem. Make sure you have a good engine ground. The Powermaster is a good starter. I had one on a 94 Corvette that I got from Summit when the original starter went out. Worked great.

Also make sure your battery cables and especially the end terminals are in good condition. Increasing the gauge of the cables will help a lot.

A lighter starter will only be cured with a different starter motor, but as suggested, perhaps other things may help the difficulty turning the engine. Any starter works better when it gets all the voltage it was designed for.

After having my 455 rebuilt and mildly modified the original starter was found to be worn out. I bought a "rebuilt" through NAPA which turned out to be defective.

I then started looking at hi torque mini starters and wound up at the Summit site. I opted for Summit's generic starter which looked and spec'd like a Powermaster and was less expensive. I also purchased a wrap around blanket to insurlate it from exhaust and block heat.

It has worked well for about a year now but you have to pay attention to the install which is not just a "bolt it up and go" proposition. There is a reason they specify a fairly precise clearance between starter and ring gear teeth and supply a packet of shims to help you achieve that clearance. Too little and it will bind. Too much and you risk shearing from not enough engagement.

I had to install, check clearance, insert a few shims, check again, drop starter, check, drop etc until I had used all but one shim to get the clearance specified. I was thankful it was a lighter weight mini starter.

The Summit mini starter spins the 455 like it had no compression. I also used heavier battery cable since I was coming from the trunk of the car as well as a heavier wire from the remote Ford type solenoid which is also in the trunk.

If I were to do another project car I would not hesitate to use the Summit mini starter, insulating blanket and a heavier battery cable.

I know you read a bad review or two, but many folks on here use the Powermaster, or a clone like the Summit model with great success. I have one, not wrapped, on my track pack car, with headers, running over 10:1 compression and it always spins like a champ. For me, it bolted right up with no shims necessary, but YMMV.

I like the RobbMc starter.

I have the Powermaster 9610 in my Olds 350 with headers , no heat wrap, no starter heat shield.
Haven't had any heat or starting issues in 4 years.
I would recommend the Powermaster.

I've got the 9510 as well, BBO W manifolds 8 yo battery but new cables and good tight connections fires up w no problems. Fit right w out shims but comes w shims and IIRC starter bolts too.
