Despite the fact that the 350 Pontiac engine generally garners little attention in the hobby, HPP still receives a fair amount of questions regarding building them up. Some owners want to retain numbers-matching block status and add some tire-smoking power, and others desire to be different and not simply perform a traditional 400 or 455 swap in an effort to increase performance.
For those who fit into either category, Ken "Ace" Brewer from Pacific Performance Racing (PPR) has an answer. PPR, home of Tomahawk Performance Products, has just released a brand new 4.00-inch stroker package for the plentiful and very-inexpensive-to-buy 350 engine that transforms it into a 383-cube thumper. Follow the recipe outlined here, and you can look forward to 462 horsepower at 6,100-rpm and 436 lb-ft of torque at 4,400 rpm. The beautiful part is that the combination employs a lightweight reciprocating assembly for a quicker rate of rev, a 9.6:1 compression ratio for pump gas, valve sizes that quiet the old complaint of too much shrouding in the small bores, and it's affordable. How affordable? Does $1,595.95 (under $1,400 with 5140 rods) for a complete balanced Ultra Lite rotating assembly with forged pistons and forged steel rods ring your bell?
Some of you may be asking, why not just build a 400? That's a reasonable question, assuming you have one at the ready. But the fact that few Pontiac hobbyists seem to want 350s makes cores very cheap, if not free, and the 350/383 could be considered the underdog in any race against a larger engine from any camp, so there is the spoiler factor as well. If nothing else, Pontiac fans have a new number to play with.
Think how much fun it will be upstaging the Bowtie and Mopar brigades, who owned exclusive 383 bragging rights...until now. Remember, this thing actually cranks out some power. If it didn't, we wouldn't waste time telling you about it. Now go pull a 350 out of the scrap bin and get started!
What is the part # to the kit?
I have a 74 GTO PONTIAC 350, AND IT'S STRIPPED DOWN TO THE BLOCK. CAN YOU'LL REBUILD TO A 383 CUBIC FOR ME, AND AT WHAT PRICE? THANKS.
