i have used both the cometic and felpro mls gaskets and prefer the felpro because they have a single sealing ring between cylinder (400 chev) which in turned has more clamping load in that area. I use VHT copper gasket spray and make sure the surface finish is correct. I use cbn & pcd type tooli...

i have used a product called seal-all head & block sealer the company that makes it is seal-lock international dresher PA . for best results, pressurize the head, the product doesnt cross link until you bake it in an oven @ 200 deg for 4 hours. I have had great sucess with it. It has sealed up p...

i had a sb chev motown block hot honed at a absorberant rate, i had a issue with cranckcase pressure with low tension rings and pulled down the eng , torque plated it and 6 strokes you couldnt see the benefit, no windows it was spotless I think with a thick wall block like the dart & world produ...

I know of a 351c over here that use to run a single dominator, max rpm i think was 7800, the intake was filled thou and they were factory 4Vs, cfm was great,but the heads had no velocity, had to rev the crap out of it, application was drag racing. Oh it had .800 + camlift made bit over 600hp You hav...

500hp from a set of fuelies in street use might be a stretch, would require 383/400 cubes. Im not sure what you guys over there achieve, i have a 355 with 11.2 comp,462s 1.980/ 1.5in that flowed 220cfm @ 25in, solid cam .550/530 254/260 produced 468 hp, I think from memory it cost about $4000 NZ but...

We race anti-clockwise over here with torque loading of the engine, the car has a natural tendancy to hang the ass out. Our combination is the only car in the country that is reverse rotation. So when the torque is applied the car has a natural tendancy to turn left and hug the pole line. It has the...

hi there wolf, i had a set of RHS 23 deg heads that i plugged and redrilled to suit a T & D 14deg rocker stand as i was on a time line and waiting 12-16 weeks wasnt an option. The RHS 23deg heads require .100 in longer valves, also anglarity/loading of the pushrod ( sideways) you have to take in...

Well i think the aussies spend alot of time looking at the direction of swirl in the toilet as drink more than we do

pehaps a side draft in panama would work a treat

fishman you are 100% correct about gravitational pull. Now you know what happens when you assume!

i have a four barrel helix carb spacer, with reference to the flow direction, in the southern hemisphere the direction is the wrong way. I may be clutching at straws here but are going to get one cncd & test to see if there is any relevence. just to clarify what im refering to, try to look at wa...

yes it is a brasswell with an adapter plate underneath to straighten the carb to level, this in itself creates issues as the plenum is to big and velocity/signal strength is less, troy would have a laugh at the system we used to fix the distribution. This is going abit off subject, i will start anot...

hi there JV, in our application the engine sits on the side as they had a problem with the inside running lean with the g forces on the oval track. The bottom bank is basically at 90 deg and the engine has a very low C.O.G we could drop a pressure section out as we do flood the bottom bank. The engi...

because of the round rocker shaft & pedestal you cant use flat shim stock, the shims actually taper up the sides so you still maintain the support. I am aiming for .020-.045 in preload.

thanks for the contacts ed & CJ

In our circle track engine sb 406 we scavenge out of the valley as well, 4 stage pump 2 scavenge 2 pressure. The engine is totally sealed with a 3 vane vac pump pulling around 7in, a breather is remotely mounted off the dry sump tank, with a drop down catch can/seperator. Rings are childs & albe...

We are running a braswell on our oval track 406 it has been modified with dual float set ups with .120 needle valves. We were suffering from fuel starvation in the corners and the dual float set up fixed the problem. During testing with a data recorder and g sensors pulling 1.5 gs in the corners. Be...

can anyone help on a good source for some rocker shims for a 360 Chrysler, they usually come in 3 sizes .020, .040 and .060 in. We require .040 in for this one job. I have exhausted all the sources over here and they said they are on back order. The other alternative if i cant locate any shims is .0...
