looks like i will be building a 406 small block for great white at some point. i am picking up an early 70's 4 bolt main 400 block from a local engine builder. good deal at 300 bucks. :D

You just had to outdo me didn't you Doug? :rofl:

Are you building it up yourself?

did'nt start out that way greg :rofl: those blocks in good shape just don't come up often. i'll start collecting parts for it and i think i'll get dean to build the short block. that way he can machine it to the rotating assembly i buy for it.

I found out I have an Eagle stroker kit in mine.

Here's some reading for you Doug.

i plan to use this camshaft along with the afr 180 straight plug heads. at this time i don't know if i will be using a 65 or 75cc chamber. it will depend on the volume of the piston dish to get the compression ratio i want. rough calculations of different piston/chamber/gasket combos put the comp ratio in the 9.5 to 9.8-1 range. 91 octane with the aluminum heads will be ok. it should be a very strong performer from off idle to 5500 rpm. my intake manifold, edelbrock performer 3701, won't have the breath to go much beyond that, afterall it is strictly a street car and i have no interest in revving beyond that. :D

Watch your intake closing point on your cam...keep your dynamic compression ratio between 8:1 and 9:1 and you should be fine on pump gas.

Are you keeping your stock TH350 transmission?
 
What's the closing point of the intake valve with that cam Doug. I looked on the website for Howard's Cams and couldn't find that information. A similar specked Comp Cam has a fairly late closing of 61 degrees; with 75cc chambers you end up with a lackluster dynamic ratio of about 7:1. You could afford to go with 65cc chambers and get a dynamic ratio of about 8:1 or pick a cam with an earlier closing to build more torque.
 
From our experience with a stock turbo 350 behind a mild 454 will last a couple of years. You might want to look for a turbo 400 to put in at the same time. Guess who might just have one and the price is right.

my calculations show a dynamic cr of 8.11-1 and a static ratio of 9.8-1. this cam in a big inch small block should give about 14-15 inches of vacuum and idle reasonably well.
 
the camshaft specs are
http://www.summitracing.com/int/parts/hrs-cl113215-10/overview/make/chevrolet
intake closes at 61* , overlap of 54*
the pistons are flat tops -6cc
bore-4.155
stroke-3.75
rods-5.7
edelbrock 3701 with [ fake ] egr
q-jet carb
headers 1 5/8 primary 3" collector, X-crossover,2 1/2" pipes,raptor glasspacks [ for my inner teenager :rofl: ] and a pair of cats.
we are thinking it should pull like a bear to 5500. :D
so far i have the block, manifold,carb,headers,X-pipe,and mufflers.
this will be an ongoing thing as i have to be careful with the house building budget until i get the lakehouse sold. i have to keep enough aside for the racecar too. :eek:
 
based on previous 406 [quite a few of em'] small blocks that dean has built we are estimating torque in the range of 500 lb's at around 4000 rpm. no hard launches for great white, the stock rear will likely twist right out from under the car. :eek: in his stockpile of stuff dean has a set of lightly used 1.5 stainless roller rockers that will be going in the afr's.

I'm not sure how he does it, but Chris Straub has the knack for picking the right cam for any given combination. Some times, a lesser cam works a lot better. He seems to have a lot of happy customers. I bought some Ferrea valves from him a few years ago. Pleasant and informative on the phone too.
