350 with 9.75 comp, trick flow heads, 750dp, perform rpm intake, xe274 using 1.5 rr , 1 5/8 longtube hedders. http://videos.streetfire.net/video/n...tor_171260.htm

 

sounds good! whats it idling at?

 

800

 

I like how he romps the throttle and it moves the camera.
You probably need to advance the timing on it. It will need to be much earlier timing than stock.

 

its set at 36 deg all in at 2500

 

whats the idle timing set to? i wish i could get my car to idle smoothly at 800 but i think its not gonna happen. It needs 900 but i havent finished the tune. I got like 26 degrees at idle

 

That's what I was hinting at. The best timing depends on the cam and the DCR.
Stock timing is like 6° base and 36° all in at 2500.
That cam will probably like something around 18° base and 38° all in at 3000.
(that is, unless you like the "about-to-die" exhaust sound)
Orr89, is your cam bigger than a 280?

 

its 286/306 advertised.. 230/245 at .050". i have run 23 degrees and it idled on it but was searchin alot so i bumped it up and it liked it abit better. I have other issues causing the searching so if i figure all that out, i'll go play with timing

 

Yea, that one isn't going to want to play nice. Mine is only 224@.050 but has a 108° LSA. It likes 24° at a 800 idle, you just can't turn the A/C on unless it is set to 900.

 

Good luck with those XE grinds... I had 2 of them XE274's fail on me

 

mines on a 109 and its a roller cam tho so it idles abit smoother than say a flat tappet, but it aint that smooth


Intex1982, did that car hit 12's yet?
is it running better than before?

 

I have almost exactly the same combo as you do (200cc World heads, and different headers though) and mine seems very happy with about 16* mechanical at idle, and it idles even better with the vacuum advance hooked up as well (its in the 20's with it hooked up).

 

Don't you just hate it when it dumps all that powdered metal in the engine ? Hopefully he broke it in right. At least he didn't start off with 1.6 rockers...

 

just got this motor runing friday taking it to track next friday. but it never hit 12 before my old car did with my old motor. i had to idle it up to 1000 its loading up bad.

well i break it in the way comp cam said to.

 

If it's a flat tappet and you coated it with plenty of jiz, dump the oil & filter after running it a couple of hours, before heading to the track.
I know, I'm just stating the obvious...

 

Sounds awesome. Can I take a guess and say 40 series muffler[s]?

 

coated it with plenty of jiz put (2 packs) , comp cam oil addive too and used 30w non detgent oil . let run at 2000-2500 for 30mins then let run 15 more at idle. then changed oil and filter.

yea 40's

 

problem with flat tappets is that modern oils are featuring less and less zinc and phosphorous i believe which help lubricate parts better. Since most cars are now rollers or overhead cam setups with roller parts, they can get away with less zince and such.

now is the time to convert to rollers.
