emorybritt 13 Report post Posted April 14, 2016 I recently dropped in a ATK HP06 Ford 302 base engine 300hp. I want to do some mild/cheap upgrades nothing serious or a real project. I was wondering what would the best roller rockers be? Also, what would some similar upgrades be? I'm looking to make the most hp out of this but on a small budget and also without having my car off the road for long.

69RavenConv 286 Report post Posted April 14, 2016 I went with these (or something very similar) on my engine. Mine's the original 302 with a retrofit roller cam. My specs are very similar to yours, my cam is a little hotter but maybe a 300 HP engine on a good day. I would think they would work for you and won't break the bank. http://www.compperformancegroupstores.com/store/merchant.mvc?Screen=PROD&Store_Code=CC&Product_Code=1431-16&Category_Code=MagnumRoller Quote Share this post Link to post Share on other sites

Just making sure because I've been browsing craigslist and want to make sure. Also, have you or anyone noticed any gains? Or just a more reliable engine?

barnett468 418 Report post Posted April 14, 2016 SCORPION If you want more power, buy 1.7 ratio but you should have a least 3.25 gears. You can also mill the heads to increase compression but will need to use thinner head gaskets to improve the quenc clearance. . Quote Share this post Link to post Share on other sites
Rsanter 152 Report post Posted April 14, 2016 No, not a any 1.6 ratio arm will work. There is ratio but there are also dimensions too. It has to be for a ford small block like you have. If your engine came with a mild cam, I would agree with the 1.7 ratio giving it a little bump. Some people prefer to put the 1.6 on the intake and the 1.7 on the exhaust to give the ford small exhaust side a little help Someone used to sell the rocker sets like that Also, do,you have adjustable or bolt down rockers?

Bob As far as I know they are bolt down. And as far as milling the heads, what all does that entail? Remember, I am on a low budget and can't have my car off the road for a long period of time. I currently do not have 3.25 gears I have 2.80 with a T5 tranny but if I was planning on re-gearing would it be bad to run the 1.7 ratio rockers until I upgraded the gears?

Rsanter 152 Report post Posted April 15, 2016 You do not need to mill the heads for roller rockers, you just need to order the correct stuff for your application. If running stockish hydronic cam you can use the bolt down roller rockers no problem. There is also a stud kit that avoids milling. You can run what you have for now and add the roller rockers later, no issues Where are you located? Perhaps you can do some swapping with a member for a gear set better suited to what you want Bob Quote Share this post Link to post Share on other sites
machm1970 180 Report post Posted April 15, 2016 One more thing to be mindful of, depending on what you have you may need different valve covers. Many of them won't fit under the stamped steel covers. matt Quote Share this post Link to post Share on other sites
Silver-Fox 3 Report post Posted April 15, 2016 Personally I wouldn't waste my money on just roller tip rockers like the ones suggested above without some other engine modifications. True performance Roller Rocker have needle bearings at the fulcrum point on the stud as well as a roller at the tip. Most of the friction (loss) gain is at the fulcrum point not the tip. An upgraded cam for the 302 is not that expensive and with the addition of true roller rockers you should then see a performance kick....just my 2 cents.

I've have Crane Gold Race roller rocker arms on one of my vehicles. On my Mach 1 I have had Comp Pro Magnum roller rocker arms and now Scorpion roller rocker arms. Of these three the Scorpion's are by far much better quality, and the Comp Pro Magnums were the worst, in my opinion. Quote Share this post Link to post Share on other sites
emorybritt 13 Report post Posted April 18, 2016 Well the reason I am asking is because I want to do some upgrades and get a little more power. So if I can't do rocker arms until I Re-gear, what would be some similar upgrades. Going with the cam idea, what would be a suggestion for a new camshaft? And would I have to do anything else when swapping the cam? I am in charlotte, nc. I have a 9" housing sitting at home just waiting for a gear set as well. Im unaware of the pricing of gears? Also I've heard that rear ends aren't a novice job and if so I would have to factor in the price of a mechanic putting that together. Any other ideas on how to get the most out of this setup on a budget? Quote Share this post Link to post Share on other sites
barnett468 418 Report post Posted April 18, 2016 . In general, the "bigger" the cam is, the numerically higher the gears need to be, so you are limited with what you can do with your current gear ratio, and the only real "budget" way to get more power out of it is set the carb secondarys so they open at the optimal time and set the timing curve so it is optimal for your setup. There simply is no "budget" way to making a significant increase in power. If you want roller rockers to get a noticeable increase in power, save your money because they will not do that. Higher ratio rockers will, but again, it's better if you change your gears if you go to higher ratios. Quote Share this post Link to post Share on other sites
