How many have ran the T/A hemikiller cam and whats your opinion on it. I am building a street 455 for a restoration on my 69 stgae1- 4speed car and would like a cam with a good buick sound but no just plan stock. For years I ran a old spx-2 cam and liked it ,but its was a little to hard for whats going to be a Friday/Saturday cruiser, plus I have had the cam for years. Even though I plan on driving it a lot-I HOPE. My build is a 10.5 wiesco piston ,ported iron heads(unshroud and port work), stage1 valves, stock valve train(with adj pushrods),stock rods, eldelbrock aluminum intake, holley 850 dp., stock stage 1 fuel pump, with stock fuel tank and lines Thanks
The SP2X was 230/240/110. Not sure what you mean by it being a "little to hard", but if you mean too big, the Hemi Killer is even bigger. It is 241/241/110. It's a single pattern cam more suited to Stage2 heads, but if your heads are really good, it should be OK. The SP2X has the same specs as the TA 284-94H except for the wider lobe center of 114. http://www.taperformance.com/proddetail.asp?prod=TA_288-94H The 114 LCA would tame it down from the SP2X if that is what you are looking for. TA recommends roller rockers for the Hemi Killer. http://www.taperformance.com/proddetail.asp?prod=TA_298H
On my spx-2 the idle was just a little high to keep it running good, but I also had it with a automatic not a 4-speed,and I felt like it lost some of that buick rumble. Also I forgot to say,I was running old mickey Thompson headers and now will be running stock manifolds
In that case, I would not run a single pattern cam. You'll want the 10* or more increased exhaust duration to help out exhaust flow with restrictive stock exhaust manifolds. Have you considered the 118 cam? http://www.taperformance.com/proddetail.asp?prod=TA_C118-455
Narrower lobe centers make bigger top end power, but they also increase overlap which means lower idle vacuum, and rockier idle. A wider lobe center increases idle vacuum which means better idle. the 118 will have a better idle and flatter torque curve. The 113 is a really nice cam, it will have a rougher idle, and nice power. It might be a better choice for you.
Would,'t the TA 288-94 114 "good idle" be equal in power to the 113, but have an idle like a 118 "good idle"? That is my guess, but would like to get an experienced opinion.
I am running the TA 290-94H I like it. Idles fine and you can use stock valve train short of the springs. If you want to hear how different cams sound a lot of them are on you tube videos.
I ran the 413. It has a little aggressive idle. Vacuum is good for brakes. Runs great. Need valve springs and a converter if automatic.
Thanks for the info, I do not have power brakes, but probably will later, and I'm running a 4-speed. I am looking for a good idle, not to aggressive.
I've heard a lot of good things about the TA 288-94h for a street driven car. 230/240/114. I have no experience with it yet, have one sitting in a box at my house waiting to go in. I think JW has installed a lot of these. You can call TA and get some really good info from them and no pressure to buy.
Anyone ran the 284-88H? I was planning to use that with my 430 build. Narrower lobe center, at 110*, I didn't think it would make it too radical sounding based off of sound clips online.
Here's a update on the engine build-Have all the machine work done, bearings and etc.., bought and paid for. Have the heads completed, with TA1435A springs, new locks and retainers. Now just the need the cam and gasket set. I would love to use my old school Mickey Thompson headers that I've had for years, but its looks as if they are going to hit the 4-speed crossmember. Just about to buy the cam and let the building begin. Any last thoughts or new testimonials since last year on cam selection, and/or exhaust headers vs stock maifolds
Do you know for sure what your compression ratio will be? Don't guess. It is very common for the MT headers to hit the transmission cross member at the rear flange. Just clearance the cross member.
