There is an extremely easy way to convince everyone of a JH-V8's capability: Build one. Build one, take it to car shows and campaign it ...   05-24-2010 10:54 pm

Back in the late 1980s Porsche ran an ad for the 944 Turbo showing every part differentiating it from the standard 944....let's just say the ...   05-24-2010 04:07 pm

In realative terms 10sec is not all that uncommon.  A running modification was made to the accessory housing in mid 1974 (oil bleed hole) to ...   02-14-2010 03:25 pm

They are easy enough to replace.  Bruce Madden in Atlanta, GA has a large stock of them. ...   02-14-2010 03:21 pm

Ask John Cronin for the dyno plot we did on his identical build...I'm thinking the smiles for this combination are getting contageous.  ...   01-15-2010 11:55 pm

Sounds like a fairly typical issue. Floats may be stuck and/or gross-jets may be clogged w varnish, etc. A full rebuild may not ...   01-04-2010 02:58 pm

http://jhppg.com/gallery/main.php?g2_itemId=30265 In my research I found the guys that sell oil pumps and accessories suggest a minimum of 10AN fittings.  I did use 8AN for the ...   12-28-2009 12:19 am

You may need to add a few spacer to the driver's side engine mount. ...   12-17-2009 04:31 pm

Interesting... I'm wondering if this is the same bellhousing used in the Eclat 2.2 (?) which would be extremely rare.  This variant from the factory used the ...   12-16-2009 06:55 pm

Having access to the original Lotus shim kit with every shim between .050" and .130" AND an 8mm helicoil kit to fix those stripped studs ...   12-16-2009 12:46 am

The short answer is no.  The line + fittings are specific British Whitworth(sp?) items that are close to 1/8" NPT but not close enough for ...   12-02-2009 09:40 pm

Contact Bruce Madden in Atlanta, GA 404-261-2552 ...   11-22-2009 03:33 pm

:) There are a number of critical dimensions and quirks not mentioned in the shop manual that took me blowing up four of my own engines ...   11-12-2009 11:49 pm

Thanks Kurt....this story is one of a dozen or so over the years I've seen that explains why I take great pride in knowing every ...   11-09-2009 01:05 am

Kurt, The re-grinds have a smaller base-circle to get more lift (you can't really add material to the toe of the cam), no worries, it's common ...   11-01-2009 03:24 pm

Put me on that distribution list!   ...   10-21-2009 04:46 pm

Edward, When tightening the bearings, you may want to inspect the hub and the spindle for wear first.  I made the mistake of over-tightening a wheel ...   10-06-2009 12:38 am

Edward, Be sure to coat the threads of the flywheel bolts upon reassembly.  It only took me three transmission changes to figure that's where a lot ...   10-06-2009 12:34 am

Just say no to forced induction with the 907... A few brave souls have slapped on super-chargers and I know of at least one person who ...   09-14-2009 07:07 pm

Opinions will differ, but I'm not a fan of the flexible mounting hardware on the Dellortos due to my past experiences...Strombers are a different story.  ...   09-14-2009 12:57 pm

As Jody and Dan have pointed out, the usual suspects are the deteriorated rubber bushings in the upper shaft joint (the fix is bronze) and the nylon/delrin ...   08-07-2009 02:59 pm

Rebar and Angle Iron... My similar story is continuously welding two 3/4"x3/4"x1/8" pieces of angle iron down the "frame rails" to tie the front and rear suspension ...   07-16-2009 08:31 pm

John, You actually don't want everything in the powertrain lined-up perfectly.  Sounds strange, yes, but a little out-of-line wobble is necessary to keep the bearings in ...   07-15-2009 09:21 pm

All - John hinted at the beginnings of this little adolescent side-show "...i know this gets discussed...but I never saw an answer" Like all good Americans, I ...   05-30-2009 06:41 am

Tim, We've had the opportunity to disagree in the past.  I do have the data with which to base my claims, and to date you haven't ...   05-28-2009 07:01 pm

John, There really is very little emperical data (dyno runs) to differentiate the various combinations of cams, sprockets, carbs and ignition settings.  However, thanks to people like Tim the ...   05-26-2009 03:09 am

What?  I thought the whole idea of a sports-car was for it to always have wildly uncontrollable oversteer???? or is that just indicative of 911s? ...   05-19-2009 02:24 pm

Once the two short bolts are out you can rotate the retaining plate to expose the ears.  It is a tight fit and there is ...   04-22-2009 12:09 am

There is a rarely used adjustment screw on the shaft mating the brake booster to the master cylinder.  You may need to back it out ...   04-15-2009 04:45 pm

What you've got is a band-aid solution.  While it may be running, it's not running well and it's certainly not taking advantage of the Crane's ...   04-13-2009 03:46 pm

Gary, Upon assembling that engine I set the Exhaust on the high side of .012" and the Intake to the high side of .007" dry.  Same thing I ...   04-06-2009 01:11 am

In upgrading the brakes to deal with bigger and stickier rubber, you'll also want to upgrade the frickin tiny JH ball joints and wheel bearings.  ...   03-20-2009 03:48 pm

As J-man points out, look for the obvious out of spec / worn items.  When I first got my JH it was about as easy ...   03-13-2009 03:23 pm

Verify it is not the oil pressure gauge take-off fitting located in the same area.  No it wont stop regardless of which fitting it's coming ...   03-08-2009 08:43 pm

Congrats on gettting her started - now comes the fun part! A "1973" model could have either  late MkI or early MkII block.  Both blocks have ...   03-08-2009 07:14 pm

PAECO has been around for a long time.  I found their extensive catalog extremely helpful in learning the technical aspects of engine building, but I've never ...   03-05-2009 04:20 pm

Brett is correct in that the shaft is held together with shear-pins made from plastic, for safety sakes I would not retrofit a steel cotter-pin.  ...   03-02-2009 08:41 pm

How about posting that dyno run so we can compare the shape of the torque curve to John Cronin's recent dyno run??? I solved my leakage problem by ...   02-24-2009 04:02 pm

Chris, Your best bet for a kit is as JHRV8 suggests and going to a modern hot rod source and find something that will fit.  The ...   02-12-2009 03:05 pm

Ollie, Congrats on the K&N upgrade, I think you'll find access to the distributor, oil filter, wiring harness, etc. will be MUCH easier! The most common mistake ...   01-25-2009 05:38 pm
