305h comp cam 525/525 lift anybody out there use this camshaft?

Hello

Just wondering if anybody out there has ever used the 305h comp cam 525/525 lift 305_Dur camshaft???? if so did they get the job done? /rev/sound/ produce good hp with all the matched parts of course...

I have used the 292h comp 501 lift before in a flat top 355 with 1.6 rockers and a good set of camel humps and that was a very strong engine that would rev 6500rpm with no trouble at all........... also of course in the same block i have used the lunati bracket master 515/515 lift camshaft and it also did a great job!!!!
Im just thinking about trying something different and going with the 305h 525 lift comp in my 406sbc........
SO anyone out there using the 305h? let me know!!! thanks everyone

Why such a large cam? If my application required a cam of those specs...I would be running a solid cam instead of a hydraulic.

thats not a huge lift but the dur. is quite a bit for the street unless were you live there are not speed limits and you can cruise at 3500 rpm and not in first gear lol.but if you live were there is traffic the 305h is probably not what you want to go to the store with.don't get me wrong i like the lope of the cam but is the gear going to put the rpm's in the range to get the most of the cam.what are you looking to do or get out of the engine?

I have installed the 305H in a few customers engines per their request. It is large, has a rough idle and has weak torque until the R's are up. One engine was a 406 w/12 to 1 comp., aluminum heads, and was backed by a 4 spd. He was running 4.56's and a 28" tall tire. He specifically wanted a hydraulic cam and it ran rather well. It was a bracket racer that he took to the local cruise ins.
The other was a 383 bracket race engine. It saw no street time at all. Same scenario. The customer wanted to run a hydraulic cam. In both cases it seemed to work well as long as all the proper equipment was used.

I buddy had a 305h in a 327 flat top motor & 462 (1.94-1.5 valved) heads in a 68 chevell with a 4 speed & 3.55 gears. It ran like a rapped ape!! I thought about it in my 406, but went with a solid lift instead.

Also, I've ran similarly sized cams in the same engine with one being solid lift & the other hydraulic, & really couldn't feel the difference in power. I'm sure the solid made more, just couldn't really feel it.

Hello,,, i have heard that you have to degree the 305h cam no matter what,,,,,

i know its for the best to degree any cam, but the say it dont have a advance built in the cam so its a most??

what would be the difference between a 515/515 bracket master cam which sorry to say but i didnt degree it in and it ran just fine against the 525/525 not degreeing it in, would it really hurt it that bad not degreeing ??

any idea's on what there talking about saying the 305h not having a advance built in it?? any help would be great thanks!!!
