CHESTNUTXE 7,299 Posted September 12, 2018 making good progress! sorry about that pic above in wrong thread lolThis is what i forgot to check when taking the engine apart ,how far down the hole the pistons are and im glad ol m8 didnt shave the block cause it must be so close to zero deck i guess by 1990s fords machining had gone high computerized compared to older blocks which could be up to 040 down the holeSent from my SM-G570Y using Tapatalk Share this post Link to post Share on other sites

NZXD 2,328 Posted September 13, 2018 I FOUND A NOS CAM ON E BAY,4TZ 6250 B i checked its spec and its a 480 lift with 224 @50 ,is a xr8 au camshaft,should be ok as not a monster cam.not bad for $250,looking at around $450 -550 for a crow or others.That’s a Ford Racing/Motorsport grind, B303, it’s not a factory AU XR8 cam. Nothing from the Ford factory came with that much duration at 50. The factory ECU won’t like it, unless you run a carb or chip...Sent from my iPhone using Tapatalk 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites
CHESTNUTXE 7,299 Posted September 13, 2018 Yup i didnt buy it i bought a smaller cam with 110 lobe sep and 1500 5500 rpmThat’s a Ford Racing/Motorsport grind, B303, it’s not a factory AU XR8 cam.

CHESTNUTXE 7,299 Posted September 14, 2018 With no more parts to finish it off i just thought to see how much piston to valve clearance there is so i put the head on and wowned it over and even with 5 thou piston poking out of the bore there was heaps off room even without the headgasket onThis no 3 main cap bolt has a threaded end for maybe a fox body sump pick up i guess i accidentally painted it thinking it was a head bolt also just waiting on the new roller cam ,chain is ready.Sent from my SM-G570Y using TapatalkSent from my SM-G570Y using Tapatalk Share this post Link to post Share on other sites

bear351c 10,270 Posted September 16, 2018 Comp cams know their product, if they say no lube, then no lube. As it's got rollers, you want them to turn, not skip. 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites
CHESTNUTXE 7,299 Posted September 16, 2018 remember the xw wagon on skippy,white with burgandy interior,ahhh if hammond only new about the 302 roller cam. Share this post Link to post Share on other sites
NZXD 2,328 Posted September 16, 2018 Yeah the rule of thumb on a few 5.0 forums is the block we’re good for 500hp at the crank....but in saying that a Australian tuning place on Facebook get 550hp at the wheels with no issues out of the 302 block with boost...also depends on the tune and revs. The other point was that they didn’t like high rpm, I take mine to 6500 a bit once to 7000 and no issues. The later 351 roller blocks made in the 1990s split the cam tunnels really bad too. Maybe it’s just luck of the draw with them. Turns out that the 289 I scored is a 302, much disappointment.
