    Hey Eric, getting El Camino back this week , I had 4.10 Eaton posi with new ring and pinion...cost a arm and leg. I'm wanting to make it to test and tune at local drag strip but I don't want to hit it to hard until I put some frame support of some kind underneath .....I have seen the cal track ? and I have a QA1 book they have drag packages but for now I want to brace what is absolutely necessary before a trip down the track....the gears set me back over 2 grand so I was wondering where to start ......Thanks a ton for the help.....

    hi eric - yes i pretty much followed your advice on the stall :) but i dont think mentioning that is worth it, too many trolls about and frankly it doesnt really matter. Im still sure you know a few tons worth than me about this stuff anyway - so i still highly value your input! im only into this for a few recent years and the amount of knowledge to absorb is staggering - oneday ill hopefully be able to master building a semi decent car myself..

    thanks again for very valuable input despite how it worked out for me :)

    '68-79 Nova will be 60" wide wheel mount to wheel mount, '70-81 Camaro /Firebird will be 61". The 70-81 Camaro/Firebird and '72-79 Nova will be the 8.5" 10-bolt, a good rear with many of the Z28's having a 3.42 gear in them...but gears are really cheap for the 8.5" 10 bolt, only about $150. Z28's and Trans Ams are most common to find a factory Posi, Nova's not so much inless it is a '72-74 SS Nova
    The 67-69 Camaro and '68-71 Nova have the 8.2" 10-bolt, a much weaker rear that I don't recommend, but it is still stronger than the stock older style 8.2" drop-out type in the '55. The '66-67 Nova 12-bolt will be 58" wide, but is extremely hard to find anymore.

    Well it is going to be a street/strip (strip would be driving it to the track not on the track) truck so that small amount of extra HP is not going to be worth spending the money on. And the block has been punched but I don't know how far, so I'm thinking bout .060 if it ain't already there. The block feels like there's enough meat there to not have the overheating problem....thnx

    I've got a couple of good engine modeling programs, and could never get the added higher cost of the bigger than 383/385/388 common stroker to be worth the added $650-1200 expense for the 25-40 hp it might add. If it was for a race class where every last HP was needed to even be competitive it might be different, but for common street/strip or bracket race use it didn't pay to try to stretch them bigger than 388 (which is .060" over and 3.75" crank.)

    So best bet is not to go over a 3.73" stroke....right? In your opinion is there really that much difference in power or performance.

    Depends on what block you have, the early 2-piece seal blocks limit is about 3-3/4" stroke(basic 383/385/388" depending on overbore), you can do 396/398/402" using a 3-7/8" stroke but this generally cost much more as crank has to have smaller 2.000" rod journals )2.100" is standerd large journal)and you need to use a small journal rod that is made on a specific forging blank to be smaller overall on the big end so it will clear the block, and quite often you will hit water jacket when clearancing the block for this set up(about 1 in 6 blocks). The newer 1-piece seal block take this a little better, but still a chance of hitting water(about 1 in 10 blocks).

    Stock 350 SBC, what is the largest stroke crank can I go with and what length of rods with what type of pistons and will I have to use a particular type of rings. This is going to be my 1st stroker motor so all help and advice would be appreciated.

    Well the last s10 I did had the 450s set up on it and didn't really do to bad but I understand what you are saying. I think I'm going to go with a team G topped off with a mighty demon 850. This way i dont have to worry bout screwing up on cutting the hole in the scoop. Now I just gotta sell the ram.
