Well not an awful lot to start with, but a couple of pics (didnt want my grinding work of sunday to go unseen!), smoothed pretty much the whole lot of the valley for faster oil drainage onto the cam and got rid of some of the nasty flash from the casting on the rest of the block, and did a little mock up as wanted to see how tall the lump is going to be!!! Beats working on Mini's!!!
The donor... engineless

half polished

polished!

The mock up!!!

Looking good, did you get a periscope to aid forward vision?

Wow. I think you may have to cut a hole in the bonnet

Not sure, if I mount it low enough it may only stick out like, a foot

Did roughly measure it- it should only stick out about 200mm (the scoop & carb)

I'm thinking this is going to loose its handling abilities!!! Drag racing here we come! May as well ditch the double wishbone suspension on the rear and put a big jag axle in!

An example..........Capri fitted with a 4-71 on a RV8

.........................You don't need a Periscope to see straight ahead

You can see everything perfect whats in front of you and next of you on the right side ( in my case the opposite side...as I drive on the other side of the road)

Every thing else...well .....what you don't see..ehhh...what you don't miss...
Should warn you for the rain, be shure you'll have the right key next to your chair to turn the scoop backwards when it starts to rain.
It will deffo catch too much water causing the engine to stall. I found out the hard way

Without the foam/mesh filter the blower will breath much easyer as I found out on the dyno. Just use a good round K&N style filter.

Liking it!
Wasn't planning on taking it out in the rain- but that might be a bit hard living in England

the scoop came with a thin rough foam filter behind the lovely chrome mesh (for the bugs) and also with a round filter for inside, which I will be changing for a k&n methinks

Here you go olly, you may have to look hard for the 2 oil drain holes as they are as far down in the corners of the oil puddles as possible!

Pleased with the high temp wrinkle paint on the rockers- gives a factory type serious finish

is there a dimension for drilling for the cam retainer plate?
as i have a plate, but need to drill my block to suit,

topcatcustom · Post by **topcatcustom** » Tue Nov 04, 2008 6:04 pm

Dont have one I'm afraid, can try and measure it but hard to get a reference point! Is it not just an offer it up and mark type job?

cheers for that TC. I've poste some of my block in the other thread.

Started milling stuff for the SC manifold today as got the mill cross feed motor fixed (after not bothering since got it!) and the cuts are just so satisfying!

Thick old stuff!

Finally a small chunk of visible progress! I finally nearly finished my inlet manifold and I am very happy with it- lots of thanks to Nigel @ uk blowers and blown v8 (if he is still on here!) for the advice!

My old milling machine got through the lump of ally plate I found ok, and hopefully my tig is leak free..! I welded both sides of everything so will hopefully be fine...

All I have to do to the manifold is get in there with the die grinder and open up the ports a little, and give the whole thing a bit of a polish! Here are the pics:

I also ordered my blower cam from real steel today, so will pop it in the lathe and machine the lip for the retaining plate when it comes through- will try and finish off my heads this weekend, then I have to order the DV springs and get them into the machine shop to get the seats modified to take them! Once that is done its trial fit and geometry setting- fun

did you not try v8tuner for the cam?

topcatcustom · Post by **topcatcustom** » Fri Jan 30, 2009 8:05 pm

I had seen it on their site- but was a little put off by not much info whereas real steel had the full spec, plus Perry had said he was very happy with his! Will be ordering the rhodes lifters, springs and retainers and push rods from V8 Tuner tho
