1776 Engine build

Post by wizard 1066 » Sun Sep 13, 2015 12:36 pm

Just started to collect parts for a rebuild, 1776 engine, planning to build it over the next couple of weeks of spare time as and when parts are delivered, starting with a AB block AS41 case we had in the garage, having it cut to take the 1776 B+P and heads, looking to keep it usable so no wild cam or carbs, just enough of a boost to keep up with regular traffic, scat cam, lifters and valve springs, twin 34s, and new exhaust, should do the trick.

Hi
I wouldn't bother with a scat cam or any other performance cam,just keep the standard camshaft for a 1776.
that's my tip for you .
Good luck
Cheers
Paul

sounds good, a scat c25 is a good bus cam plenty of low down torque or if you want a bit more zoom c35 thats what i run in mine

I was going to put a C35 in but advise from others suggested the C25 would be better suited, I put my list of parts together from recomendations from other engine builders, the scat C25 should give the engine a bit more low down power as you said, the kit also includes cam followers and heavy duty valve springs, the carbs we have are set up for a 1776 and after a bit of cleaning up on the manifolds should be good to go, the heads have been worked on before so I hope the valve guides are still OK.
I stripped and cleaned the block today and going to have the block and crank checked for the new bearings, was thinking for trying to ballance the internals con rods, pistons etc.

balance the bottom end is a really good idea it runs so much smoother and itl last longer, if you can afford a new case i would go for that after my experience.

Got a delivery today of the parts for the build from machine 7, the kit includes cam, HD valve springs and caps, HD cam followers and running in lube, already had the case done to fit the 1776, crank done new cam and crank bearings.
Image
Case assembley with lube on the bearing and cam lobes, used (wellseal) jointing compound for the case joint as its a good product.
Image
Assembled all the crank making sure they are all the same way up (see notch on conrod), also making sure they are numbered on the rod correctly and right way round paired up.
Image
Putting the case half together and finaly torqing the nuts to the required setting and checking that everything turns easily, first stage complete.

Been looking at ways to keep the engine cool now it's running a bigger block, been told that the 914 oil cooler bolts on the same way as the origional dog house, with some modification to the back of the fan housing, being slightly wider than the standard one holds more oil and cools better.

Are they HD single springs, or dual springs?

No deep sump? No external oil filter?

Does a deep sump have an advantage on cooling Jim? I always assumed so by adding extra capacity through which to dissipate heat but recently I read that is not the case, it just prevents starvation in higher revving engines

Both.

The sump is in the air flow as you drive, so a cooling effect. More oil in the sump, so has an easier life. Far better filtration with modern filters.

Interesting Jim (& obvious when you think about it) I've just pulled out my (alleged) 1776 tonight ..I have oil temp & pressure issues with it so might knock it down to machine the case for full flow. You should deffo look to do that now Wizard. Having brought it in the bus, stripping it down a bit is the only way I can think to see what it is. I might well build it back up then with a stroker crank

Looking at adding a deep sump on my 1600 to aid cooling, do you still run a stock oil strainer?

Kit came with single HD valve springs as I don't expect it to be reving it hard, so should be up to the job, might consider the deep sump but what about clearance on a lowered van, don't want to rip it off over speed bumps.
