I had a 68 318cid (stock like 230hp) with a bunch of bolt-on
in my 68 Charger
while my 440 was out, 513cid engine was being built
I didn't make a lot of money back then,
took time to gather parts & $$$ I was making like $6.15 an hr
I didn't want to be without a car,
I had a 318/904 combo & drive shaft (new u-joints)
I took out of another car, another 68 Charger, parts car
it was a 2bbl engine, it had a good compression test
I put some swap meet Lunati 284/0.484 lift cam
& cheap hyd. lifters, from the local Monument Auto parts place I worked
bolted on a swap meet $25 Edelbrock LD-340 alum 4bbl manifold
a $25 600cfm Holley 1450 Vacuum secondary, jetted up a tad
with a heat insulator/spacer under it, Velocity stack (wahoo),
so the scoop above it would work well still
a set of $25 swap meet cheapo 1-3/4" Heddman headers
I Gerry-rigged them up to my old 2-1/4" dual factory exhaust
from my BB 440, that had headers already
an Accel Super Coil IIRC/hooter coil, good plug wires
stock distributor, a little cooler plugs
all in the exact same car (68 Charger R/T) I ran my 440cid in for years
way back in my Concord street racing days
I beat many a BB car with 5.13:1 gears in that heavy ol' Charger
with that lowly lil' 318 LA engine
I went back to the 4.56:1 gears, when I put the 513cid in it
still beat a shitload of cars, for a couple years, until it spun a rod bearing
my buddy Rocco wanted to race, he had a 69 RR,
he was always broke
IIRC it was a 383cid with a tunnel ram 2 center squirter Holley carbs
typical 70's build, (over carbed) 4 speed,
he had some gears IIRC I loaned him
(I always had a couple sets/pumkins ready)
& a Lunati 297/0.477 hydraulic cam, I also gave him out of my ol' 440
his had big tube 2" Hooker headers, slip together POS's
he thought it was fast/quick
we lined up out on some industrial road somewhere
& all of a sudden, he acted like his car was having electrical issues
because every time we launched
I had him by 3-4 cars already by about 120 ft out
he'd turn off his lights, tell me it's having electrical issues
he finally told/admitted to me much later, decade later;
"he just didn't want to get beat by a lowly 318"
carry on nothing to see here
