A 69 351 isn't any stronger than any other 351w. It has a shorter deck. A 69 351 w has a 9.480 deck height.
What all from the 302 can be used in the 393? can i use my cam ect??Look....the common consensus here is to build the 351. Even n/a a 393 will meet your power goals.
Once you get this thing making decent power n/a, with a decent set of heads, put your blower on it. You built the one intake, build another. ( I know a guy that has to build his own intakes, and he recently built a whole different system despite the fact that he a really good looking, perfectly working piece already).
The "drop in another stock block 5.0, transfer your stuff over, and run it till it blows" is flawed...Do you really want to have to do this over again?
A 351 has a wider deck. There will be more room for the injector rails, and the blower itself It's gonna make more torque even at n/a. you won't have to blow 11-12 psi into it to get to the 5.0 block killing 500ft lbs. You'l have your looks, you'll have your sound. And, if you found a stock bore 69 casting, what's stopping you?
Exactly why I noted all that in my explanation . It isn’t just building a short block or a long block for that matter I had that notion at one time . Never the case.Yeah let's pump the brakes a bit, after a nice long discussion over the phone with a few members I think I am going to just fix what I have.
This is why, it's all going into a convertible. I don't race the car except for very occasionally. If I do this monster engine that needs heads ect ect... were in balls deep at 5k+ for a long block... now what? Oh yeah that t5 ain't gonna hold now I need a trans, 4lug 28 spline c clip axles wont do the job. Now the car needs structural reinforcement to handle and plant all that power..... the snowball keep on rolling.
I don't think I need a dart block anymore, I think I need a better machinist.
Again even with a 393 . You use a cam and heads for a 302 , you get 302 results for more effort to make it all work .What all from the 302 can be used in the 393? can i use my cam ect??
yes i am in Florida.... the 2 351 factory sealed engines look tempting..... swap the heads and cam some link lifters and spacers for my blower.... swap pan ect... and have parts to sell off.Exactly why I noted all that in my explanation . It isn’t just building a short block or a long block for that matter I had that notion at one time . Never the case.
Find a real machinist . You’re In Florida judging by the craigslist add you shared ? Take the short block to MPR .
Avoid anything that has been in salt water.found this deal.... I wonder what they use in the short block on these???
