I've got a 69 351 w I'm wanting to build. Looking for any tips or mods I can do to make cheap horse power. Thanks
How much money do you have?
What do you intend to do with the engine? (Pump gas or Race gas)
Hey buddy, ya I know I can build a nice motor for around 7 grand. I'm looking to use pump gas. I'm building a 74 F100 short bed. Chop'n the top and slam'n it on the ground.Trying to build a fun shop truck plus I wan't to try and get some half way descent gas mileage ( ya I know ha ha ha ) I'll be doing alot of highway traveling mostly. I'm not really looking to get a 10 sec. truck, I just want a fun, tire smok'n, and plenty of pep when I hit the gas pedal. Yes juice is also on my mind. I've got a few hipo goodies already.
My 351 Combo - on the cheap
I shopped good used parts for a couple years,
put together a 351 w/good torque and decent
power that gets good mileage.
Started with a lo miles (30k) shortblock in
good condition, no cyl ridge. 95 Lightning,
so has the good marine / hi perf "football" rods.
8.8 cr w/stock GT40 iron heads, but found
good lo miles used of Ebrock 1.9 intake heads
for $600. Now ~9.2 cr. Believe will be able
to run on 87 after dyno tune. Sat awhile,
so put in new moly rings and std bearings
and dbl roller timing set. Oil pump gears
weren't the best so put in new std pump.
Being factory roller block, (all 351's 94-up)
I picked up good used 5.0 hydr roller lifters
& the hold down hardware. Bought lo miles
5.0 stock hydr roller cam $50, upped the lift
to .477 with good used 1.72 ratio roller rockers.
The cam's 050 duration (~210/214) put the
torque peak around 4k, and makes very good
torque virtually from off idle. Desktop dyno
(I know, optimistic) put it with a good dyno tune
(coming) at 375 hp @ 5k, 420 tq @ 4k, 375 tq @ 2.5k.
Nice, broad torque curve for 4000 lb Linc Mk VII
w/3:55 gears. Have a beefed auto and 2500
lockup stall. Matches the torque curve nicely.
Comp cams makes some great hydr flat tappet
cams if you don't have a roller block. Not near
as much $ as converting a non-roller block to
roller lifters. I'd look in the 050 range of
210 to near 220 w/hi .400's lift or just over .500.
Being my car is efi, I converted to mass air w/used
Ford 70mm air meter made for stock Stang
computer & 30 lb inj's (also found them good
used). Still need to dyno tune, though.
I picked up used GT40-351 lower and mated it
to a used Explorer (like Cobra) upper. Another
great efi setup is an Ebrock 351 Perf lower which
works with any Ebrock efi Perf. upper so could
look for used upper if you want to go efi.
I've helped a friend put an Ebrock Perf intake
& 650 Holley (you can find them used quite
reasonable) on a full size Bronco some years
ago and the difference was flat amazing!
Would make a good setup. Probly find an
intake used cheap too. Would help keep
your low & mid range torque up, and rev
nicely to over 5k.
The icing on the cake is that with a 4,000
lb car and 3:55's, driving 80 mph I get 21.5
mpg even in hilly country.
I got most of my "critical" parts from the
classifieds on corral.net & now stangnet also
has good classifieds. I was careful what
I bought on ebay, shied away from cams,
lifters, injectors, stuff that has to "work"
Stuff like headers, gaskets, etc not as big

Good afternoon sorry for bugging in
I need some help please specially for the pro techs, or engineers.
I have a 2001 impala that's not supercharge, and has the 3800 series 2 engine, I basically want to supercharge this 2001 impala.
If i buy a supercharger for the 3800 series 2 engine, do i have to do anything to the engine to handle the extra HP.
After buying and installing the bolt in supercharger do i have to do anything to the ECU and how can i do it.
Where can i get this parts?
I'll apreciate your answer. thanks!!!
