Hello, Have any of you on this forum used a Howard's Camshaft? I have talked with Mark/cutlassefi,Lynn@Mondello,Dick@Dick Miller Racing,Chris @Engle during my quest to explore camshaft options..Have to say that I am impressed(at least for now) with the fact that all of their grinds are done in house and are checked for rockwell hardness and the max cams carry a 5yr.warranty...(per.their website)-(Reasonably priced also) Am I being a little overzealous here?as very few cams researched until now are not hardened let alone checked to ensure hardness) I will post the spec's on a cam that I am considering which appears to bear similarities to the other recomendations that I received from the others listed above:::Copy/paste spec's did not transfer as labeled): part #511431-12 adv.duration 281/287 duration @.050 227/233 lift with 1.60 rockers 512/512 lobe seperation 110 intake centerline 108 (flat tappet)( to be used in 455 Olds ) looking for a noticeable lope/chop@ idle,enough vacuum for power brakes, performer intake, "c" heads with 1.72/2.07 stainless valves,headers,9.5-10.0 compresion goal,(want to run pump gas) .030 over bore ,built 2004r tranny with 2500-2800 stall, 3.73 gears with posi..(will be a weekender/show car...

Im running that cam right now it's great im running it in a 355 I built. It has really good midrange power. I can give more details on my build and drive train if you want.

That sounds nice in your sbo! I know that it will not hit like that in my bbo ! I really like the way it sounds at idle...Keep me posted on the road manners/highway performance of it ,,if you don't mind..Thanks

coppercutlass

It drives great I have almost 200 miles on it. It idles great in traffic, cruises nice and smooth, has plenty of vac. for brakes. Tons of power and throttle response . one quick tap of the throttle and the tires are up In smoke.

Cool, Sounds like a cam that I may want to consider after all for my 455!

That cam will NOT sound or be the same in a BBO with 100 more cubic inches!
It'll mellow down a lot!

I may have to contact them and get the next grind up! Thanks

coppercutlass

The cam may not sound as aggressive in the 455 but it's perfect for the 3.73 gear and the stall he wants to run and compression . Im running the same gear and a 2800 stall. Something in the 540 lift 240 duration should sound similar to what I have. I had a 462 for a short time with a came with specs in that region and it sound just as aggressive as the one in my sbo much louder and had 11 to 1 compression.

Coppercutlass, I called Howards Cams today and give them all the build data/details that I currently have and this is what they recommended for my application: CL510041-10 Adv. dur.289/299 dur.@.050 235/245 520/544 lift..This is a tadd more ( lift and duration)than what cutlassefi,and Engle had quoted me on! I questioned "John" at Howards cam about vacuum for power brakes and he stated that it would not be an issue with this grind...John also said that I would have some chop at idle! (I am glad of that).How close is this one to yours?

coppercutlass

close on which one ? im running the 512 lift cam u mentioned. On the 461 I had it was 532 lift 232 duration . I looked up the paper work from when I bought it. Motor is long gone but that's thing sounded nasty. it was 11 to 1 compression. there is a video online from the guy who originally built it let me find it .

coppercutlass

here ya go. I wish I didn't have to get rid of the car or the motor but that's life atleast I got my 72 .

panther80

That olds sounds good! How did it perform in low to mid range? Thanks for the video!

coppercutlass

I ran great, that 4000 lb pig ran into the 11's

I am still considering the erson TQ50 that cutlassefi recommended, the howards profile sounds good also, but get this....I have come across a Crower that has a lower rpm initial range than the howards...here are the spec's that I haveart number 56264 229/236 @.050 dur. 112 lobe seperation, 520/528 lift...rpm 1600-4800 (with up to 6000 op. range) moderate lope at idle..
