#693905 00whitelightning (User) Fresh Boarder Posts: 94 Engine mods 4 Years, 4 Months ago   OK guys, like always i am never satisfied with the bike. I have recently purchased Speedstar Hi-Comp pistons (10.25:1), 1700 cams to be given a hotrod grind from looney, and heavy duty valve springs. Ive been told i will be adjustable pushrods and new lifters but i am not sure where i should be looking for these items. Also, does anyone know what kind of performance changes i should see from these upgrades?? I got all the parts for cheap (only about $225 so for the above mentioned parts) looking at another $250 for the regrind but just trying to find pushrods and lifters. Help please guys!   Logged     Last Edit: 2013/10/03 19:13 By 00whitelightning.     The administrator has disabled public write access. #693922 jd750ace (User) Front toward enemy Platinum Boarder Posts: 18763 Re:Engine mods 4 Years, 4 Months ago   High performance Mopar lifters for a 318? I have HT-2011 lifters in mine. Don't know if there needs to be a particular upgrade to the lifter body for HC and a bumper cam. A couple of the mods know.......   Logged       The administrator has disabled public write access. #693966 blue_star (User) Platinum Boarder Posts: 6570 Re:Engine mods 4 Years, 4 Months ago   Will 1700 cams work in a 1600 motor?   Logged       The administrator has disabled public write access. #694017 jd750ace (User) Front toward enemy Platinum Boarder Posts: 18763 Re:Engine mods 4 Years, 4 Months ago   For some reason I'm thinking the Warrior cams will but the straight 1700 won't. I put stock 1600 cams back in mine.   Logged       The administrator has disabled public write access. #694026 texasscott1 (User) Two of a kind Platinum Boarder Posts: 4486 Re:Engine mods 4 Years, 4 Months ago   I've read that the HC pistons bring on their own set of problems. The Road Star doesn't need more compression to run better. The best bang for the buck is the Speedstar roller cams L & D has for the 1600. http://www.ldcustombikewurks.com/looneycams.htm   Logged     Last Edit: 2013/10/04 06:45 By texasscott1.   My 99 Standard Test Mule Scott B.   The administrator has disabled public write access. #694038 smokescreens (User) lifes better riding twins Platinum Boarder Posts: 17430 Re:Engine mods 4 Years, 4 Months ago   texasscott1 wrote: I've read that the HC pistons bring on their own set of problems.

One of the bikes I looked at before I settled for my 01 was a 99 with a 1775 kit and cam(s) His dyno sheet was 93 hp 124 ft lbs, with a stock carb (jetted obviously) I was quite close to buying it, but it was ridden HARD so I decided against it.   Logged     Repugnant is a creature who would squander the ability to lift an eye to heaven, conscious of his fleeting time here   The administrator has disabled public write access. #694050 davej (User) Platinum Boarder Posts: 18167 Re:Engine mods 4 Years, 4 Months ago   smokescreens wrote: texasscott1 wrote: I've read that the HC pistons bring on their own set of problems.

If anyone ever tells you to stack head gaskets end your conversation with them about anything mechanical.   Logged     dave   The administrator has disabled public write access. #694056 fastjohnny (User) Platinum Boarder Posts: 1780 Re:Engine mods 4 Years, 4 Months ago   davej wrote: smokescreens wrote: texasscott1 wrote: I've read that the HC pistons bring on their own set of problems.

Also the HC upgrade requires premium gas and if the Dyna is used to back off on the timing then some of the gain goes away. Hard cranking is another consideration. L.A. Sleeve has Nikasil liner kits up to 113 ci. Like they say - nothing beats displacement. I've dealt with them and they are very good at what they do.   Logged     My 99 Standard Test Mule Scott B.   The administrator has disabled public write access.
