So I just finished installing my new 4” stroke engine and I got ti thinking about timing . Nothing changed but the 4” crank . Will my timing curve be different? Piston speed will be faster so will I need to advance my timing throughout the rpm curve ? Curious…

Priming my new build and I am not getting oil to the rockers or sending unit . Engine is a magnum based 408. Lifter galley plugs ( including the one in front of intermediate shaft ) are installed front and rear . Plug above rear main is in . Plug under oil filter is in . Oil filter filled with...

My block is in the shop getting a 4” assembly and I am curious as to how the 4” stroke will change its performance characteristics. In my 360 it had a bit of a lopey idle and great midrange. Not so much on the high end but I think that was due to valvetrain issues . Compression will be around...

I flew out to MN to help my brother install a freshly ported top end on his 69 400 Firebird and we adjusted the valves using the EOIC method . On the last cylinder I realized I was turning the crank in reverse rotation! LOL. So I readjusted cylinder 1 going clockwise and found no difference...

I am building a mild 408 with a cast 4” crank and my machinist doesn’t like the condition of the old balancer . Any recommendations for an aftermarket balancer ? It will be externally balanced . Scat crank rods and pistons . Factory 5.9 flex plate . I understand these can be hard to balance ...

Any opinions on scat cast crank for hot daily driver ? Installing a 46rh install my Barracuda and while out I pulled the rear main cap to install new main seal . The bearings looked a bit iffy so I decided to replace them. Then I got thinking I should just get a 4” crank since I already have...

While replacing the main seal on my engine, I took a look at the bearing on the rear cap and wanted some opinions on it .

I am installing a new main seal while my engine is out for the 46rh install and I want to replace the pan gasket as well . I can’t remember if can use the one piece pan gasket …. Engine is a 98 5.9 with LA timing chain cover . Is there a particular one to use ?

I pulled a 360 out of a 91 B250 last fall and while breaking it down this morning I discovered that had a windage tray and a double roller timing chain set . Was this normal ?

I am working on getting the tune right on my 408 and every so often I get a whacking sound . Its as if someone rapped my aluminum intake with a small hammer. Only happens every 30 seconds or so unless I rev the engine ...then it happens every 10 seconds or so and is more frequent as engine get...

Well did I help it or ruin it ? My engine produced a little less HP than I expected and fell off at 6200 rpms so after mulling it over I decided it was most likely due to the intake .

3 good indicators 1. He had a set of W2 Dyno headers on the wall 2. Has a Sun Distributor Machine and knows how to use it 3 Says he will tune for low and high speed. Frank has been around a while... take a look at this awesome Sun dizzy machine

I came up with this today while installing my rockers . Its always a pain keeping the pushrods positioned while torqueing down the shafts.

I am reassembling my engine after blowing a freeze plug and replacing bearings because I didnt like the look of them and I wanted to double check the oiling system due to what I considered insufficient flow to the top end. Oil pump was gone thru , all galleys cleaned , cam bearings checked for...

Blew a freeze plug and decided to tear down the engine to check head geskets , bore and bearings . Engine had very few hours and I think the freeze plug blew due to me using rtv on install vs adhesive like Indian head . Bearings look to have more wear than they should for maybe 3 hrs of run...

I sold a W2 M1 dual plane intake to a member but cant remember who it was ... maybe Cpearce ? Anyway I am eager to find out how it performed . Anyone else run this combo before ?

Why are oil pump drives so expensive ? Seem crazy... almost as much as a custom roller cam !

Quick question before I pull my lifters out... Do solid rollers care which lobe the were on ? Or which bore they were in ? If so I will store them accordingly untill reassembly . In the past I just pulled and tossed in a box but I thought I would ask .

I blew a freeze plug a few weeks ago and decided to pull the engine so I could check for a blown head gasket. Here is a pic of the head between #5 & 7.

I took my Swinger for a quick drive yesterday and got on it for the first time since building the car . It hit 7k pretty quick then I could smell coolant . Luckily I was 1/4 mile from home . I popped a heater hose off on an earlier test drive but attributed that to the idiot that assembled the...

I am going to ball to ball oil thru pushrods because I wasnt comfortable with the amount of oil getting to the pushrods via the shafts . And since this is a 7500+ rpm capable engine I would feel better with oil coming from both ends. How does the adjuster position look to you ? This it at...

Getting close on this project . Still need to finish bodywork and paint but the engine is going . Did some baseline tuning this weekend . Here isa little sound bite . Idling @ 930 rpm , 18* initial and 32 total . Trying to link to facebook video but not sure how to . Thing sounds...

I am finally getting around to assembling my W2 Stroker and primed it tonight. I am not getting oil flowing out of the drivers side rockers. I am turning the crank by hand then priming ...then turning crank another 1/8 turn... then priming again. Is it just that the cam hole is not lined up ?

I am degreeing the solid roller cam on my stroker tonight and the cam card is different than the other I have had. Help me figure out if I have this thing degreed correctly. The actual #s I am getting straight up is int open= 19.7ish int close= 47.7ish ex open = 56 ex close= 14.5 Lift...
